app.net, paid social network

I never really understood the value of "web 2.0", or at least of its main face, FaceBook. In fact I don't like it. It seems confusing and pointless to me.
But somebody is making a paid social network, app.net, and least one point makes sense: if the users are paying, they will work trying to please the users, and if advertisers are paying, they work trying to please the advertisers.
