@brewsterkahle @tomjennings @cyberlyra I know this is kind of a rhetorical question, but:
when designing the social web, we stopped at the federated model (many servers, no gatekeeping to join the network, clients access own server) typical of email and other Internet protocols.
I understand the attraction of shifting down another level, connecting clients peer-to-peer, but it is a seriously hairy technical challenge without visible benefit to users.
