Several months ago, Meebo added an “unofficial” connection to Facebook chat. Backwards engineering Facebook's chat system proved unstable, and it was later pulled. Well, after working through official channels with Facebook and their API, Meebo has officially added Facebook Chat integration once again.
Facebook chat integration requires that you have a Facebook account (of course) but allows you to connect and chat even when you're not signed into the Facebook website.
With the addition of Facebook, Meebo now supports a total of ten IM networks:
- Meebo chat rooms
- AIM/AOL Instant Messenger
- Yahoo! Messenger
- Windows Live Messenger (MSN Messenger)
- Google Talk
- and now, Facebook
