TweetDeckTweetDeck Apps and Social Commerce App Flattr Felled by Twitter’s API Rules (SocialTimes)
In its ongoing efforts to police how its data is used by third-party apps, Twitter has announced it would shut down mobile TweetDeck apps, Facebook integration with TweetDeck and use of the social commerce app Flattr on its platform on May 7. TweetDeck is a Twitter client acquired by Twitter in 2011. The Next Web Twitter has said that TweetDeck for Mac and PC will stick around for now and to closely follow the feature updates that the Web and Chrome versions of the app debut. Those Web editions will be the primary TweetDeck experience and will get rollouts of new Twitter stuff sooner. CNET The decision appears largely intended to get people to solely use the official Twitter for iPhone and Android applications, which proffer a consistent Twitter experience that is more in line with what people find on the company’s website. The Verge The TweetDeck update comes a day after Twitter said it would discontinue support for Internet Explorer 6 and 7. The feature lets publishers and developers embed tweets and Twitter buttons on their websites. TweetDeck Blog A post from the TweetDeck blog reads: “Over the past few years, we’ve seen a steady trend towards people using TweetDeck on their computers and Twitter on their mobile devices. This trend coincides with an increased investment in Twitter for iPhone and Twitter for Android –– adding photo filters and other editing capabilities, revamping user profiles and enhancing search. That said, we know this applies to most of our users –– not all of them. And for those of you who are inconvenienced by this shift, our sincere apologies.”

Syrian Electronic Army Hacks Again, This Time it’s CBS’ 60 Minutes (VentureBeat)
The Syrian Electronic Army, a group of pro-regime hackers, reportedly took over the Twitter account of CBS’ 60 Minutes as well as other CBS brands Saturday, saying the United States is “in bed” with terrorists. This is the second Twitter take-over in the last week for the SEA, which often attacks publications for their coverage of the situation in Syria. AllThingsD The group, which claimed credit for the attacks via a statement on its website, has a history of attacking websites and social media accounts of various western media organizations. On April 16, it attacked websites and some Twitter accounts belonging to NPR. Last month, it attacked the website and Twitter account of Human Rights Watch. Gizmodo Of course all this could just go away if Twitter would roll out some two-step verification, but who knows how long that’ll take. Any bets as to how many more high-profile hacks we’ll have to see?
