Based on my experience during 1.0, I've been speculating a fall-out relatively soon as I've seen a lot of me-too popups from the critical areas (SF/NY). Roughly 1 year after this influx in 1.0, the bottom fell out. During 2.0 that pattern was contradicted as social bees tend to migrate and have a lot less loyalty. Friendster > MySpace > Facebook is one example, and there have been a quite a few other. However, is it really a great migration or simply natural segregation at work? I'm beginning to think it's the latter and that being said, maybe there is a play to be made for the me-too sites this time around.
