I just upgraded my TweetDeck to the newest beta with Facebook integration. Here is an except from the post at TweetDeck’s posterous:

As the title suggests, v0.24.1 includes the first elements of Facebook integration into TweetDeck. This integration consists of two elements.

Firstly you can click on the Facebook icon at the top and, once you have signed into Facebook and given TweetDeck authorisation, this will add a new column full of each of your friends most recent status update which updates automatically once a minute.
