And to add to that, some more bad news for TweetDeck lovers, no more Facebook integration, so you will not be able to update your Facebook status from TweetDeck any more. So are we seeing a slow death of TweetDeck, well its not going to end because it is the official Twitter client available for Windows user, the mac users have another official app and TweetDeck as well.
TweetDeck is the only option for Twitter for Windows and the web at the moment and it doesn't look like it is ending any time soon. But in the real sense TweetDeck is already dead and its now just another Twitter client that happen to be just the official one.
