In a blog post, TweetDeck says it has been focusing on building a fast and feature-rich web application that will work best on modern browsers. Could it have something to do with the demise of Posterous (which was supposed to topple blogging and everything else as the ultimate tool of personal web expression, according to "guru" Steve Rubel - some call him the "Sally Struthers" of the Infobahn)? Likely so!
TD ::: "(W)e’re going to focus our development efforts on our modern, web-based versions of TweetDeck. To that end, we are discontinuing support for our older apps: TweetDeck AIR, TweetDeck for Android and TweetDeck for iPhone. They will be removed from their respective app stores in early May and will stop functioning shortly thereafter. We’ll also discontinue support for our Facebook integration."
Twitter apologised to users. TweetDeck says its apps for AIR, Android and iPhone rely on v1.0 of Twitter’s API, which will be retired starting this month.
