We all act as peers in a large social structure in the current world. I have heard about the idea of P2P social networks several times. However, the trend seem to be going in the opposite direction: Look at the cloud. I would think the majority of Facebook users would not see the need for having an always-on server in their own home hosting their social network, and therefore have a hard time imagining that "P2P social [networking] is the future". They would either have to have this in their own home, or rented from some company, costing money, and, once again, centralising information.
