Yelp, from a co-creator of paypal. Interesting. I think. I never really understood what friendster was about, so I don't really know. Someone should try it out, though, and include me in the ask list. I probably won't have an answer. (Although this kind of stuff is why it's so hard to have a public e-mail address and a personal e-mail address.)
