Good points, however I think once the novelty of justin.tv wears of, viewers will stray. That already seems to be happening. But that's OK for justin - because their business model is to sell this solution to others, and they've already proved it works. On the other hand, Upstream is more of a social network type site that takes facebook stalking to a new level. I envision people using it to keep tabs on what their friends are up to. Who knows if it'll work, though.
