The site is really sexy, i like it. However I don't think it matters. Social media is built on fads. Myspace had its day, there once was a time when it was the "cool thing". I wouldn't be surprised if a few more users come back. However i'd be really surprised if it was any significant amount. The site, just like Digg, is a zombie. It is the living dead. You just can't make zombies into productive members of society again.
