My latest fad: Friendster. It's like a 6degrees.com thing, but you have to actually know someone to add them as a friend (except if you're adding a friend of a friend). And there's even a mechanism to allow you to play matchmakers! Kind of a fun thing, but I expect this to lose interest quickly and become like 6degrees. In any case, it's fun right now, find me and add me as a friend please!
