The problem is the vision these techno-libertarians promote is one of isolation, not connection. The world has shifted. People want to share. They want privacy, but when privacy must be eroded to allow greater connectivity, they trade it willingly.

Crypto solutions lead to technical complexity which in turn raises the barrier to entry and makes it difficult for outsiders to join in. It's some kind of isolationist community. Who uses Diaspora, anyway? Anyone? Doesn't it offer precisely what everyone's allegedly in need of?
