Social.im brings facebook Users Together Outside Browser Confinements.

A new desktop application called Social.im lets anyone with a Facebook account chat with their Facebook connections outside of the browser. Once you download and install Social.IM, (whch is only available on Windows right now), a window opens to Facebook's login page and once you login to facebook, Software pulls your friend's names and Facebook avatars into a buddy list. If your friends also have the Social.im, they will appear as available, busy, or offline, as in any other chat program.
I learned about this at Wired.
