Yeah, I thought it was strange when he first mentioned it, but when he put it in the context of a platform, I realized that it might be something bigger than just a place where geeks go and fly around.
There might be some commercial aspects to virtual worlds in the distant future.
Agreed, I think we've been seeing a slight preview of this. The recent google acquisition of lively was what brought the whole concept of virtual worlds to my attention. I'm sure that platform will serve as a testground for some ideas. I also think that possibly social networking will move into this space as well (think friends meeting up in virtual spaces) and advertising will definitely follow.
He really is an an inspiring guy.
