>I think it is completely meaningful to call it next generation (or second generation where the social graph model is the first generation).

I don't really see it. We've seen the TikTok model before in Imgur, StumbleUpon, YouTube, Reddit, Twitch, Digg, and probably others. It's mostly memes, funny videos, how-tos, and attractive women. They've hit a sweet spot of editing tools and enforced short format to provide a constant stream of quick entertainment. But I don't see anything earth shattering or ground breaking there.
