So, Facebook isn't anymore a cool new thing teenagers obsess about. Wowzers!! Does that really surprise anyone? It's not exactly a sustainable niche, kinda by definition. The real question is whether those teenagers, once grown up and less interested in beingt cool and different from their parents, will start seeing value in what Facebook offers, i.e. whether network effects in social media are cross-generational. I suspect so, since generations are not in fact discrete.
