As the title suggests, v0.24 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. From here you can email the update out to anyone, tweet it out over twitter, view the users online status and if they are online right now click on their name (or the green online status indicator) to open Facebook chat right within TweetDeck.
The other element is the ability to direct your tweet/update to post to twitter or facebook or both directly within the tweet window. Note: direct messages will not be sent via Facebook even if you have the Facebook checkbox ticked.
This release is not being pushed out to everyone right now since it is still being tested. Do feel free to install it directly from http://tweetdeck.com/beta/TweetDeck_0_24_2.air but be aware this is very beta software and is at your own risk. If you are not comfortable with this then please wait for the next major release where this functionality will be rolled up and better tested.
Want to say a huge thank-you to Dave Morin, Josh Elman & Justin Bishop from Facebook for their support and help in putting this release together. As I said earlier, this is the first step in integrated Facebook into TweetDeck and there’s a huge amount more to come.
UPDATE: following pretty much unanimous yes vote on whether to auto block message which start with @username from posting to Facebook, v0.24.1 has this functionality and is now available
UPDATE #2: some issues with expired sessions & facebook accounts where authorisation has subsequently been removed by the user are now fixed in v0.24.2
