Is there potential? I'm starting to think there is not. Many people have tried to build 3D virtual worlds, and they have all sucked -- alphaworld, worlds away, there.com, blaxun, second life. Microsoft had a big effort in this area in the mid 1990s, and I think they even made it open source (virutal worlds).

Something is being missed here, or maybe there just is "no there, there" as we said about there.com.
