HtheB: open source decentralized social network, with focus on privacy. All these aspects are completely lacking in "popular" networks like Facebook (they are closed / corporate controlled, centralized and exploit users' private data). Diaspora is not a copy, and is very different from Facebook architecturally. It's not for technical people only. Privacy and trust issues are very relevant to any "normal" user, especially these days.
