I did have the social interaction aspect in mind - acts that involve interaction with the audience are doing something that you can't get in the same way mediated by the Internet, and people will still want that experience (though getting together with a small group of friends also does it, no club or professionals involved). But there are more acts that do exactly the same thing in every show on their tour, playing off the same setlist with the same jokes in the same places. They don't have what it takes to get bookings after this is over.

But in the long run, live performance will have to interact with online world, not simply provide something separate and different. I can't imagine what forms that kind of interaction will take but I expect it's already developing.
