Definitely. Also, gamification. The platform will need more live interaction [nearly live]. The gamification can be optional; some people just want to read status updates and such. But it will be folded into a larger platofrm merging virtual reality, gaming, and various ways to interact, other than forum-style. It's not that FB is doing a bad job; they're actually doing a lot of things right. But the 'next' thing will have to be very easy to use and transformational at the same time.
