Thats pretty interesting, I hadn't heard of Orkut until you mentioned it a few posts back. I've stayed away from Myspace, Hi5, Friendster et al so far, so can't really compare what Facebook is like to them, but I have found an extraordinary number of my friends there. Its been fun messaging people from school 5 years ago who disappeared off my radar.

Like its been said, it'll go out of fashion, and I'm sure we'll all move to Orkut if Facebook make a mistake or Google bring out a killer feature.
