Web 2.0 and gaming

There's an interesting post over at Aggro Me about integrating social features (so-called "Web 2.0" features) into massive games. On some level this has already happened, as the game integrates text (and now voice) chat, friend lists, etc. But there are obviously levels and levels. AM's post explores some of those options. I especially liked the random place the comments went, talking about what kind of webpage cats would make.
