Are your friends and family split between rival social networking sites Facebook and MySpace? With hundreds of millions of users between them, these sites are hosts to a lot of communication, but since they're rivals, they don't connect with eachother; you can't message your MySpace friends from your Facebook account, for example. A web-based application called Meebo is trying to solve that problem — it now supports both services, and lets you log in through the same site and interface.

Some programs have connected the two before, but Meebo is the first one that doesn't require you to download anything. Just head over to Meebo.com and enter your user information to start chatting. One thing to keep in mind: while the site is super-friendly with MySpace, it connects to Facebook in an unofficial sort of way. So if the folks at Facebook make any big changes the way their instant messenging service works, Meebo might not be able to connect anymore.

Meebo doesn't work with any Facebook or MySpace features besides chat, but it also supports a bunch of other IM services like Yahoo!, Google Talk, and AOL Instant Messenger (AIM), and hosts its own chat rooms just for its users.
