Facebook user? Mac user? Read on.
Facile interacts with your Facebook account, allowing you to view your friends’ statuses as well as update your own. It is like Tweetie for Facebook, but uglier. Facile could use a lot more development (I don’t have the time). The source code is available at github, but I will warn you that it is very rough around the edges. It currently runs on OS X Tiger and higher.
The latest version is Facile 0.0.6.
