well, my prediction is that a new startup will appear with the intention of getting people offline. It'll start as an event organizing platform with comments.

A year or two in they'll add chat so people can keep in contact before and after the event.

A year after that it'll pretty much become a new online social network built around interests that are tied to an event, leading the company to create a new feature called, 'groups.'

... and we'll end up back where we started.
