The fact that they’d self-select an audience that agrees with them and folks that don’t wouldn’t follow them.

Bittorrent is best for static data, building it into a p2p social media protocol would be pretty hacky and would scale poorly unless it was only used for sharing media content.

What you’re looking for is a friend-2-friend network with onion routing, that way you only connect directly to people you trust and messages for others get passed along to the recipient through the f2f network.

Such things already exist, but I can’t get anyone to try out Retroshare ( http://retroshare.cc/ ) with me because it isn’t modern, polished, effortless, and mobile like corporate media.
