‘Post-PC’ is more than just marketing buzz for Apple CEO Tim Cook

Apple (AAPL) is no stranger to ditching technologies when it deems them to no longer be useful. The company dropped the floppy disk for a CD-ROM drive on the first iMac and most recently has shifted to building MacBooks and iMacs without any physical disc drives. In his first televised interview on NBC’s Rockcenter with Brian Williams, Apple CEO Tim Cook revealed that he has “ditched physical keyboards” now that he spends 80% of his time using his iPad “authoring email” and “working on things.” Cook says he’s gotten quite good at typing on the screen and advises people to trust auto-correction as it’s “quite good” — though it’s a feature we still blast iOS for some five years after the first iPhone launched. But what does it mean when the boss of the country’s most valuable company and the most revered technology company in the world doesn’t even use physical keyboards anymore? Perhaps the “post-PC” era will become mainstream sooner than we thought.

For years, Apple has touted the idea that we’re entering the “post-PC” era – a period when touchscreen-equipped smartphones and tablets will eclipse desktops, notebooks and complex operating systems as they slowly fade away into a niche reserved for professionals.

While there will still be a need for notebooks, Windows PCs and Macs, the increasing numbers of smartphones and tablets sold and continued decline of worldwide PC sales support Apple’s claim that mobile is where the next tech battleground is, even if Microsoft (MSFT) thinks otherwise.

The term “dogfooding” is often thrown around between tech blogs and Cook is doing exactly that — using his “own product to demonstrate the quality and capabilities of the product.”

As Steve Jobs once said, Apple only builds products its own engineers and designers would use themselves.

Cook’s not saying, “iPads are great” for some people and some tasks. The fact that Cook uses his iPad for 80% of his work and an iPhone all the time suggests he and Apple are serious about this post-PC era. Apple wants iPads and iPhones to be great for all of your computing needs.

Apple is serious enough about it that the big boss has shifted his habits from old-school typing on actual keyboards to using virtual keyboards. And for all we know, Cook could be using even more natural human interfaces such as more voice recognition (ex: Siri in iOS and built-in dictation in OS X Mountain Lion).

Will physical keyboards go the way of the dodo in the next handful of years? It’s doubtful, but don’t be surprised if you see fewer and fewer offices with QWERTY keyboards attached to PCs and more desks and execs just carrying tablets and a smartphone on the side.

LOS ANGELES (TheWrap.com) – Kristen Wiig is being eyed for a role in “Anchorman: The Legend Continues” for Paramount Pictures, a person familiar with the negotiations has told TheWrap.

Wiig would play opposite Steve Carell, as a love interest in the sequel. The script is still being written, and no cast beyond the principals has been set.

Adam McKay is directing the feature, which is being produced by Judd Apatow through his Apatow Productions banner. The film is a sequel to the 2004 hit, “Anchorman: The Legend of Ron Burgundy” and is due to be released in October 2013.

Best known for her work on “Saturday Night Live,” Wiig is one of the most in-demand actresses in Hollywood, since appearing in the film “Bridesmaids.” She could recently be seen at the Toronto International Film Festival in the indie feature “Imogene,” and has been busy filming a number of titles, including “The Secret Life of Walter Mitty,” and “Hateship Friendship,” with Guy Pearce.

“Anchorman: The Legend Continues” will see the original film’s cast return, including Will Ferrell, Christina Applegate, Paul Rudd and Carell. The story follows the on-set adventures of San Diego’s top newsman who is played by Ferrell. “Anchorman: The Legend of Ron Burgundy” made around $ 85 million at the box office.

Why are People so Interested in the DSM-5?

There is a lot of internet buzz about the approval by the American Psychiatric Association‘s (APA) board of trustees of its fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5.)

The APA press release notes “the trustees’ action marks the end of the manual’s comprehensive revision process, which has spanned over a decade and included contributions from more than 1,500 experts in psychiatry, psychology, social work, psychiatric nursing, pediatrics, neurology, and other related fields from 39 countries.”The approval was announced on Saturday, December 1 (was the APA trying to keep it quiet?) with publication of the DSM-5 scheduled spring 2013. For a book that has no plot or characters, its pending publication has caused great excitement. True, it is a sequel, but it is not the latest installment of Harry Potter or the Twilight Saga.Though the DSMs have not reached the volume of sales of a Harry Potter (so far), the paperback edition of the last version of the DSM had a sales rank of 261 on Amazon.com. This is remarkable for a book that is over 900 pages in length and written for professionals.Besides being bestsellers, the DSMs have inspired games and even music awards. DSM-IV the Game is available for free online. It is described as “beautiful way to engage and learn about yourself, family, and friends and as an ice breaker at your next holiday gathering.”Several years ago, Dr. Jill Squyres, a clinical psychologist in San Antonio, created the DSM-IV Music Awards for her professional society’s fall social. The DSM-IV Music Awards are modeled on the Academy Awards. She chooses categories based on a DSM diagnosis and then nominates songs that are reflective of disorders such as Major Depression (Jagged Little Pill by Alanis Morisette, King of Pain by the Police), Mania (Wake Me Up Before You Go Go by Wham, Life in the Fast Lane by the Eagles), Obsessive-Compulsive Disorder (I’m In Love With My Car by Queen, Pinball Wizard by the Who), and Borderline Personality Disorder (Isn’t life Strange by Jim Morrison, Addicted to Love by Robert Palmer).How does a medical book about psychiatric disorders inspire games and awards let alone become a bestseller? There are not enough medical professionals or people with vested interests, such as the pharmaceutical or insurance industries, to account for these sales figures. What is behind the fascination with the DSM among the general public? I believe it is because our mental state goes to the core of who we are as human beings and our fascination with the link between mental illness and creativity.Mental illness went “public” long before cancer and AIDS. Although mental illness is still considered a stigma by the general public, writers and artists have been talking publicly about their bouts of depression and struggles with alcohol and drugs for hundreds of years. Ernest Hemingway, Virginia Woolf, Sylvia Path and Vincent van Gogh committed suicide. The poets T.S. Eliot and Ezra Pound were committed to mental institutions. The 27 club is comprised of musicians who died at age 27; Janis Joplin, Jimi Hendrix, Brian Jones, Kurt Cobain, and Amy Winehouse. The public breakdowns and rants of Mel Gibson, Alec Baldwin, Lindsay Lohan, Charlie Sheen and Mel Gibson have been televised and viewed by millions on YouTube.The style and language of the DSM is another reason for its popularity. Unlike most medical textbooks , there is relatively little medical terminology and diagnoses are described in terms that are easily understandable to the nonmedical reader. Each diagnosis includes a list of symptoms, referred to as criteria, that typify the disorder. The list of symptoms is exhaustive, but not all symptoms necessarily occur in the disorder. The format and clear non-technical language invite the reader to examine and apply this new knowledge to themselves and others. A parent who worries that his child might have Attention Deficit Hyperactivity Disorder (ADHD) or a spouse concerned that their loved one is displaying symptoms of Alzheimer’s disease can easily look up these disorders and review the symptom check list.Psychiatric disorders consist of behaviors that are extreme. The same behaviors occur with less intensity or frequency in everyday living. A key symptom of Major Depression Disorder is anhedonia, a failure to find pleasure in everyday life. Anhedonia was the working title of Woody Allen’s movie Annie Hall, which won four Academy Awards including Best Picture. In mild or moderate degrees, most of us have experienced “mild anhedonia” (a.k.a being in a funk) at some point in our lives.Obsessive-compulsive disorder (OCD) is an anxiety disorder marked by obsessions, which consist of unwanted and repeated thoughts, or behaviors, and compulsions that make those with OCD feel compelled to perform a behavior to lessen their anxiety. Although most of us are not paralyzed by OCD, we all have some traits. We go back and check to see if we locked our doors or left the tea kettle on. And although we might wish to have the detective skills of Adrian Monk or the writing skills of Jack Nicholson in As Good As It Gets , these fictional characters inability to cope with OCD causes them great anguish and the inability to have significant relationships.I believe that today’s films and TV shows that portray mental illness are popular because they present characters we can relate to, unlike earlier films such as Psycho, a film that scared people so much they stopped taking showers. We laugh at the neurotic mother-son relationships portrayed in Everyone Loves Raymond and Seinfeld because we can relate to them. And we worry about our children. Are we pushing them so hard that they will end up like Natalie Portman’s crazed ballerina in the Black Swan?Brain scans have shown that that creativity and “madness” light up similar pathways in the brain. However, the overwhelming majority of mentally ill people are not artists and most artists are not mentally ill. Edgar Allen Poe, Vincent Van Gogh and Ernest Hemingway were gifted artists who happened to be mentally ill. Their mental illness did not make them artists. In fact, mental illness interferes with the artistic process. William Styron was not able to write in the throes of his depression. The mathematician John Nash did his greatest work before he was diagnosed with schizophrenia.I have no doubt that some gifted people are able to function by “throwing themselves into their art.” However, their legacy is their work, not their mental illness. People may fantasize about being able to play guitar like Jimi Hendrix, write like Hemingway, and sing and dance like Michael Jackson. But they don’t fantasize about being clinically depressed, overdosing on drugs, being homeless, or being institutionalized.To answer to my question of why we are so fascinated by the DSM, I believe it is because it presents and explains extremes of behavior, related to and connected with the more normal levels of behavior we experience. We read the DSM to find ourselves in its pages.Images: Vincent Van Gogh; Janis Joplin; MONK cover by author.

Pelosi slams House GOP for taking break amid debt talks

House Minority Leader Nancy Pelosi today ripped House Republicans for scheduling a five-day break amid the " fiscal cliff" debate, asking why the chamber is not in session "trying to build confidence" and "find common ground" with only 26 days left until a mix of steep tax hikes and spending cuts take effect.

"Here we are, Thursday in December. The talk around here is what's going on at the negotiating table. Is anything going on at the negotiating table?" Pelosi, D-Calif., wondered at her weekly news conference. "I can't even explain to my constituents why Congress isn't in session now trying to at least build bridges of understanding and representing."

The GOP-controlled House concluded legislative business Wednesday afternoon after a light floor schedule this week. House Majority Leader Eric Cantor cancelled one day of legislative business previously scheduled for today, and also cut next Friday from the calendar. Cantor, however, announced Wednesday that he has added an unspecified number of days to the legislative calendar the week of Dec. 17.

"I'm really surprised that the Republicans would leave," Pelosi said. "With all that needs to be done, [are House Republicans] avoiding the conversation? Sounds like people don't want to be in town for some reason."

At least one top House Republican, however, stayed at the Capitol: House Speaker John Boehner.

President Obama and Boehner spoke on the phone Wednesday afternoon, but no details were released about the conversation. An aide to the speaker said that "the lines of communication are open" today.

Pelosi, who said she remains in close contact with the president, has repeatedly described a Republican counter-proposal this week as "an assault" on the middle class, seniors and the country's future. She also criticized the proposal for failing to detail how Republicans would specifically achieve savings if they refused to raise tax rates on the wealthiest taxpayers.

"Why are we not here getting information?" Pelosi said. "What are we talking about here? What are we talking about when we say restructure entitlements? What does restructure mean? Destroy? Wither on the vine? Voucherize? Or does it mean let's work together to make these stronger and improve benefits for the beneficiaries?"

But with a stalemate on tax rates, even negotiations between White House and congressional staffs seem to have ground to a halt.

"It's hard to explain to anyone why there's even a mystery in the conversation that we shouldn't be having the upper 2 percent of our population paying its fair share," she said. "How do you start by saying we want to know what you're going to do to seniors before we will do what we know we have to do, which is make the wealthy pay their fair share?"

Pelosi also doubted whether the GOP proposal, which called for $600 billion in health-care savings through changes such as increasing the eligibility age for Medicare, would create adequate savings.

"Show me the money. I don't even know why that is something that people think is going to produce money. What are we going to do with people between 65 and 67?" she said. "It's not even the right thing to do, first and foremost, but is it a trophy that the Republicans want … to raise the rates for the wealthiest people in our country?"

Lawmakers return to the House for legislative business Tuesday, three weeks before the "fiscal cliff" kicks in.

The Senate is in session today.

Kathie Lee Gifford’s “Scandalous” musical to close after three weeks

LOS ANGELES (TheWrap.com) – So much for Kathie Lee Gifford‘s career as a playwright. The former “Live!” co-host’s Broadway musical “Scandalous: The Life and Times of Aimee Semple McPherson,” is shuttering a little after three weeks after it opened.

The musical, which opened November 15, will have its final performance December 9 at the Neil Simon Theatre in New York.

Gifford wrote the book and lyrics for “Scandalous,” which chronicled the life of evangelist and proto-celebrity Aimee Semple McPherson, who rose to prominence in the 1920s, only to fall from public grace amid scandalous love affairs and other controversies.

In all, “Scandalous” will have played 29 regular performances before it goes dark and 31 previews. The musical stars Carolee Carmello (left) and George Hearn, among others, and is directed by David Armstrong (“A Christmas Story the Musical,” “Catch Me if You Can”).

Though Gifford had ample opportunity to plug the production via her “Today” co-hosting duties – and she certainly took advantage of the opportunity – critics were generally unkind in their appraisal of the show.

“‘Scandalous’ isn’t so much scandalously bad as it is generic and dull,” wrote the New York Times’ Charles Isherwood.

Newsday’s Linda Winer took specific aim at Gifford’s “bombardment of nursery-rhyme lyrics.”

Talkin’ Broadway’s Matthew Murray, meanwhile, scoffed that the play “is not distinctive in one positive way.”

Asthma symptoms may vary during menstrual cycle

NEW YORK (Reuters Health) – Some women may have more or fewer asthma symptoms, such as coughing and wheezing, depending on their time of the month, a new study suggests.

Researchers said spikes and dips in estrogen and other hormones likely affect the lungs and other physiological responses involved in breathing. However, it’s still unclear whether the findings could improve doctors’ treatment of women with asthma.

The menstrual cycle “is a very important cycle… with all the biological changes and physiological things that happen,” said Dr. Samar Farha from the Cleveland Clinic, who studies asthma and other respiratory diseases but wasn’t involved in the new research.

“(Some) asthmatics describe that just before their menses, they get a worsening of their symptoms,” she told Reuters Health – but more scientific assessments of what’s going on have come to conflicting conclusions.

For the new study, researchers surveyed close to 4,000 women in Northern Europe who had normal periods and weren’t taking birth control pills.

Along with other health and lifestyle questions, they asked women to report when their last period started, as well as whether they’d had any breathing-related problems in the past three days – such as wheezing or waking up with a coughing attack.

Just under eight percent of women in the study had been diagnosed with asthma. Between two and six percent reported recent wheezing, coughing and/or shortness of breath.

Dr. Ferenc Macsali of Haukeland University Hospital in Bergen, Norway, and colleagues found the number of women with of each of those symptoms changed depending on where they were in their menstrual cycle.

For example, wheezing spiked just before and just after mid-cycle (ovulation). The dip in between corresponds to peaks in estrogen, follicle stimulating hormone and luteinizing hormone, the researchers write in the American Journal of Respiratory and Critical Care Medicine.

Complaints of shortness of breath and coughing both declined just after women got their periods, and shortness of breath was also more rare right before menses started.

Macsali’s team saw cyclical patterns in breathing symptoms in women with and without asthma.

What explains those patterns is still up for debate. Estrogen may affect the lungs directly, the researchers said. Insulin resistance and markers of general inflammation are known to vary during the menstrual cycle, which could also play a role in when breathing symptoms get better or worse.

“The observed patterns in our study are most likely a result of… complex hormonal processes,” the researchers wrote, “and it does not seem plausible that one sex hormone should explain the variation in respiratory symptoms during the menstrual cycle.”

Women with asthma should “be aware of a possibility that their symptoms are influenced by day in cycle,” Macsali told Reuters Health in an email.

Not all asthmatics will notice those changes, Farha pointed out.

For women whose symptoms do get a little worse at certain times of the month, it’s also unclear whether that ever puts them in serious danger, she added. But Farha said it may still be worth bringing up the issue with their doctor.

“It could lead to more personalized therapy, based on where their symptoms are getting worse, in which phases of their menstrual cycle,” Farha said. “You could change therapy and escalate therapy based on (those) phases.”

White House preps Plan B if debt talks fail

White House press secretary Jay Carney (Charles Dharapak/AP)President Barack Obama's budget office is preparing for the possibility that "fiscal cliff" talks will fail, triggering painful automatic cuts to domestic and defense programs that he and his Republican foes officially want to avoid. White House press secretary Jay Carney described the planning as an abundance of caution, not pessimism about the seemingly stalled negotiations.

The White House's Office of Management and Budget this week "issued a request to federal agencies" for information needed to finalize calculations on the spending cuts required under what is technically known as "sequestration," Carney told reporters at his daily briefing. OMB is "acting responsibly," he added.

"The administration remains focused on reaching agreement, as we've been discussing, on a balanced deficit-reduction plan that avoids sequestration" he said. "This action should not be read … as a change in the administration's commitment to reach an agreement and avoid sequestration."Leaders of both parties have pledged to work together in the coming weeks, and we are confident, as I just said, that we can reach an agreement. However, with less than one month left before a potential sequestration order would have to be issued, the Office of Management and Budget must take certain steps to ensure the administration is ready to issue such an order should Congress fail to act."

Carney's comments came as talks on the fiscal cliff—a series of tax hikes and government spending cuts that could plunge the economy into a new recession—seemed to be making no headway. Obama and congressional Republicans have each put a proposal on the table but do not appear to be actively involved in negotiating a compromise.

"If our offer is not acceptable to the president, then he has an obligation to show leadership by presenting a credible plan of his own that can pass both houses of Congress," Republican House Speaker John Boehner said. Boehner accused Obama of snubbing spending cuts he accepted in the past (notably in failed 2011 negotiations) and failing to lay out "serious spending cuts."

"This is preventing us from reaching an agreement," Boehner continued. "With the American economy on the brink of the fiscal cliff, we don't have time for the president to continue shifting the goal posts. We need to solve this problem."

Obama, meanwhile, flatly dismissed the idea that Republicans might use next year's vote on raising the country's debt limit as leverage in current fiscal cliff negotiations, saying it won't be entertained by the White House.

While talks between Obama and Boehner appeared to be in a deep freeze, the president and congressional leaders met separately with top executives of the Business Roundtable association in Washington. A BRT official said the group met with Republican House Majority Whip Kevin McCarthy, then Democratic Senate Finance Committee Chairman Max Baucus and Republican Sen. John Thune, who sits on the Finance and Budget committees.

BRT Chairman Jim McNerney, president and CEO of Boeing, described the discussion with Obama as "candid and constructive" and the chat with congressional leaders as "constructive."

He noted that "we encourage both sides to work around the clock, if necessary, to avoid the severe repercussions that inaction would have on U.S. economic growth and job creation."

Death toll from Philippine typhoon nears 300

NEW BATAAN, Philippines (AP) — Stunned parents searching for missing children examined a row of mud-stained bodies covered with banana leaves while survivors dried their soaked belongings on roadsides Wednesday, a day after a powerful typhoon killed nearly 300 people in the southern Philippines.

Officials fear more bodies may be found as rescuers reach hard-hit areas that were isolated by landslides, floods and downed communications.

At least 151 people died in the worst-hit province of Compostela Valley when Typhoon Bopha lashed the region Tuesday, including 78 villagers and soldiers who perished in a flash flood that swamped two emergency shelters and a military camp, provincial spokeswoman Fe Maestre said.

Disaster-response agencies reported 284 dead in the region and 14 fatalities elsewhere from the typhoon, one of the strongest to hit the country this year.

About 80 people survived the deluge in New Bataan with injuries, and Interior Secretary Mar Roxas, who visited the town, said 319 others remained missing.

“These were whole families among the registered missing,” Roxas told the ABS-CBN TV network. “Entire families may have been washed away.”

The farming town of 45,000 people was a muddy wasteland of collapsed houses and coconut and banana trees felled by Bopha’s ferocious winds.

Bodies of victims were laid on the ground for viewing by people searching for missing relatives. Some were badly mangled after being dragged by raging flood waters over rocks and other debris. A man sprayed insecticide on the remains to keep away swarms of flies.

A father wept when he found the body of his child after lifting a plastic cover. A mother, meanwhile, went away in tears, unable to find her missing children. “I have three children,” she said repeatedly, flashing three fingers before a TV cameraman.

Two men carried the mud-caked body of an unidentified girl that was covered with coconut leaves on a makeshift stretcher made from a blanket and wooden poles.

Dionisia Requinto, 43, felt lucky to have survived with her husband and their eight children after swirling flood waters surrounded their home. She said they escaped and made their way up a hill to safety, bracing themselves against boulders and fallen trees as they climbed.

“The water rose so fast,” she told AP. “It was horrible. I thought it was going to be our end.”

In nearby Davao Oriental, the coastal province first struck by the typhoon as it blew from the Pacific Ocean, at least 115 people perished, mostly in three towns that were so battered that it was hard to find any buildings with roofs remaining, provincial officer Freddie Bendulo and other officials said.

“We had a problem where to take the evacuees. All the evacuation centers have lost their roofs,” Davao Oriental Gov. Corazon Malanyaon said.

The International Federation of Red Cross and Red Crescent Societies issued an urgent appeal for $ 4.8 million to help people directly affected by the typhoon.

The sun was shining brightly for most of the day Wednesday, prompting residents to lay their soaked clothes, books and other belongings out on roadsides to dry and revealing the extent of the damage to farmland. Thousands of banana trees in one Compostela Valley plantation were toppled by the wind, the young bananas still wrapped in blue plastic covers.

But as night fell, however, rain started pouring again over New Bataan, triggering panic among some residents who feared a repeat of the previous day’s flash floods. Some carried whatever belongings they could as they hurried to nearby towns or higher ground.

After slamming into Davao Oriental and Compostela Valley, Bopha roared quickly across the southern Mindanao and central regions, knocking out power in two entire provinces, triggering landslides and leaving houses and plantations damaged. More than 170,000 fled to evacuation centers.

As of Wednesday evening, the typhoon was over the South China Sea west of Palawan province. It was blowing northwestward and could be headed to Vietnam or southern China, according to government forecasters.

The deaths came despite efforts by President Benigno Aquino III’s government to force residents out of high-risk communities as the typhoon approached.

Some 20 typhoons and storms lash the northern and central Philippines each year, but they rarely hit the vast southern Mindanao region where sprawling export banana plantations have been planted over the decades because it seldom experiences strong winds that could blow down the trees.

A rare storm in the south last December killed more than 1,200 people and left many more homeless.

The United States extended its condolences and offered to help its Asian ally deal with the typhoon’s devastation. It praised government efforts to minimize the deaths and damage.

Facebook’s Instagram cuts support for key Twitter integration

SAN FRANCISCO (Reuters) – Facebook Inc’s recently acquired photo-sharing service, Instagram, removed a key element of its integration with Twitter, signaling a deepening rift between two of the Web’s dominant social media companies.

Instagram’s Chief Executive Kevin Systrom said Wednesday his company turned off support for Twitter “cards” in order to drive Twitter users to Instagram’s own website. Twitter “cards” are a feature that allows multimedia content like YouTube videos and Instagram photos to be embedded and viewed directly within a Twitter message.

Instagram’s move marked the latest clash between Facebook and Twitter since April, when Facebook, the world’s no. 1 social network, outbid Twitter to nab fast-growing Instagram in a cash-and-stock deal valued at the time at $ 1 billion. The acquisition closed in September for roughly $ 715 million, due to Facebook’s recent stock drop.

The companies’ ties have been strained since. In July, Twitter blocked Instagram from using its data to help new Instagram users find friends.

Beginning earlier this week, Twitter’s users began to complain in public messages that Instagram photos did not seem to display properly on Twitter’s website.

Instagram CEO Kevin Systrom confirmed Wednesday that his company had decided that its users should view photos on Instagram’s own Web pages and took steps to change its policies.

“We believe the best experience is for us to link back to where the content lives,” Systrom said in a statement, citing recent improvements to Instagram’s website.

“A handful of months ago, we supported Twitter cards because we had a minimal web presence,” Systrom said, noting that the company has since released new features that allow users to comment about and “like” photos directly on Instagram’s website.

The move escalates a rivalry in the fast-growing social networking sector, where the biggest players have sought to wall off access to content from rival services and to their ranks of users. Photos are among the most popular features on both Facebook and Twitter, and Instagram’s meteoric rise in recent years has further proved how picture-sharing has become a key front in the battle for social Internet supremacy.

Instagram, which has 100 million users, allows consumers to tweak the photos they take on their smartphones and share the images with their friends, a feature that Twitter has reportedly also begun to develop. Twitter’s executive chairman Jack Dorsey was an investor in Instagram and hoped to acquire it before Facebook CEO Mark Zuckerberg tabled a successful bid.

When Zuckerberg announced the acquisition in an April blog post, he said one of Instagram’s strengths was its inter-connectivity with other social networks and pledged to continue running it as an independent service.

“We think the fact that Instagram is connected to other services beyond Facebook is an important part of the experience,” Zuckerberg wrote. “We plan on keeping features like the ability to post to other social networks.”

A Twitter spokesman declined comment Wednesday, but a status message on Twitter’s website confirmed that users are “experiencing issues,” such as “cropped images” when viewing Instagram photos on Twitter.

Systrom noted that Instagram users will be able to “continue to be able to share to Twitter as they originally did before the Twitter Cards implementation.”
