They say: TweetDeck is an Adobe Air desktop application that is currently in private beta. It aims to evolve the existing functionality of Twitter by taking an abundance of information i.e twitter feeds, and breaking it down into more manageable bite sized pieces.

This is a really great bit of kit – you can search through your own contacts Tweets or everyone’s Tweets, allows you to queue Tweets until later, create threads from replies (Plurk should start to be worried as this is one of the main advantages they had over Twitter) and more!
