A friend recently turned me onto a program that can intergrate many of the chat services that we use into one window. I liked that iChat does this somewhat, but it lacks some features that I would love to have... Primarily I hate having separate buddy lists for various accounts.
The program is Adium (http://adium.im/) and it supports a lot of differnt chat protocols, including Facebook. I think I may try it out in the coming weeks, but I welcome comments from anyone that is currently using it. If it means that I can use Facebook to keep in touch with people without having to see one more Mafia Wars or Farm update I am game to add another piece of software...
On a side note, I just figured out that I can block all posts from an app on Facebook! This may not be news to the rest of you, but I don't care that "a sheep wandered off of your farm while you were looking for the golden craps dice!"
