Facebook Wins - But Where Is My 3d Virtual Facebook World?

Sorry folks, but I think Facebook has "won" the social networking wars. The final nail in the coffin was the release of "Facebook As Platform" where now its ultimately extensible by its users. The cool thing about it is that Facebook appeals to everyone at every level - its casual enough to use for personal stuff and professional enough to post your resume into to look for a job. I've been involved in social networking sites for a long long time, I was one of the first members of Ryze, LinkedIn, and pretty much made the rounds of all the sites. But after having a profile on probably 100 sites, and different pictures everywhere, I think things are shaking out for Facebook. Plus now that they've added a video app, how much longer till we can use Facebook for real-time f2f communications? Yup, folks. Facebook is the winner.

Now where is my 3d virtual world Facebook? I'd like to see an instance of Facebook built on some 3d engine. Eric ses the Second Life engine is crap, so where do we go? Wouldn't it be cool to build a virutal world which mimics the real world and populate with real avatars? It would mimic everything expect you could teleport and fly and all sorts of other cool stuff. A world like ours, but better.
