Today, that implementation has been completed, and Facebook Chat will return to Meebo. That’s great news for users like me, who can now communicate not only with our buddies on AIM, GChat, and the other networks that Meebo supports, but also social networks (Meebo supports MySpace too). It’s also great news for Facebook, who stands to introduce the Connect concept to millions of new users, who in turn will become more comfortable as they see Facebook logins pop up on more sites around the Web.
While we don’t know exactly how much overlap there is between Meebo and Facebook users, it’s safe to assume that the number is in the millions. And while Connect is growing in popularity, big launch partners like Digg and Twitter are yet to rollout their implementations, making Meebo the biggest fish in the pond so far.
