There are many Twitter desktop clients out there, but they usually focus on your own personal timeline and that's all.

TweetDeck takes all the information contained in your Twitter account and divides it into more manageable pieces, making twittering even easier and more enjoyable. Being based on the Adobe Air platform, TweetDeck features a sleek, dark interface where you can view your twits in a three-column structure, separated by message type (regular timeline, direct messages and replies). You can even organize your Twitter contacts in groups for better handling.

Of course, TweetDeck also allows you to update your own Twitter timeline from within the program. Just click on the "Tweet" button and you'll open a text field to write.

TweetDeck is one of the most attractive Twitter clients I've tested so far. I like the way it organizes information to make it easier to read. I also loved the bottom slider that lets you choose how far the shown timeline should go. On the downside, the interface is not easily resizable and sometimes displays empty columns you apparently can't get rid of.

With TweetDeck you can follow your friends on Twitter, update your own account and organize information in a much comfortable way.
