Currently Gaia Gold is only on two social networks, Gaia Gold and now Facebook, but it offers a unique way to tie them together. Users can enter the virtual world from its main website or either of the virtual worlds, but then they're all in the same place. And that world is growing.

With platforms like Google's OpenSocial looking to make it easy to integrate content across social networks (Bebo is a part of the group), it shouldn't be hard to tie all the networks together with a virtual place. Sherman said that he definitely had eyes on OpenSocial, but so far he hasn't announced any other networks. His plans, though, are clearer: Gaia has a strong user base, Bebo has an even larger base, Facebook has an even larger base, and a network of all the other social networks, including MySpace, would have the largest user base. Now all of Facebook's users can access Gaia Online. It seems like it's only a matter of time before the virtual world appears on the others.

"We're really excited," said Sherman. "We launched on Bebo and had tremendous success. It can be much bigger on a platform like Facebook. We'll be social network agnostic and extend our network across multiple networks. From a user perspective it'll be the same, no matter what network they are using."

While other immersive virtual worlds haven't had as much success with social networks, Sherman says that Gaia's success is due in part to its light weight nature.
