"Recently Sony released the latest firmware in a long series of iterative updates. The firmware added one feature that is really worth talking about - cross game text chat. This feature is so revolutionary gamers across the globe have jumped for glee as the PSN is now more robust than Xbox Live.
Ironically, the one feature Xbox Live does not have PSN gets - cross game 'text' chat rooms (not to be confused with messaging). I've been playing around with the new chat room feature and to be honest it really is neat. Gamers can now keep up to three chat rooms active while playing any game. These chat rooms will continue to run in the background until you decide to shut them down. Each chat room can hold up to 15 friends as well."
