It looks a heck of a lot like any number of mobile messaging apps combined with subject-specific forums, in my circles. But we're relatively out of the mainstream - not in tech, but a different circle that hasn't wanted to be attached to Facebook for years.
Honestly, I think it's going to be "mobile messaging and X" where X is different for every subset of people. The mobile messaging allows you to keep contact details for people and keep in touch in a non-1-to-1 way through group chats, while the choice of X allows people to make a statement about what sort of person they are.
