TweetDeck was bought by Twitter last year and before the start of the new year, Twitter changed TweetDeck entirely. The new look was ok, but feature wise the new TweetDeck actually sux. That’s not what I say, but almost all the people I know. There are very limited features in the new TweetDeck. The New TweetDeck is a native app for Windows and MacOS whereas, the previous one was built in Adobe Air.
