I tried out Friendster last summer and it seemed pretty interesting, but when the site grew it scaled so poorly that it takes 100 years just to look someone up. Over at BoingBoing I read about Tribe.net and it beats Friendster in so many ways. The two main improvements are speed and discussion groups, called tribes, where you discuss different topics. Currently, I post in the Survivor* tribe and the BoingBoing tribe, but I’m in a lot more that I just read once and a while. Check it out.
* I get groans every time I mention I’m a fan of this season’s Survivor. I hate almost everything on TV, but I’m loving this so I don’t care.
