Social Network Software

Are there alternatives?

• Facebook
• Twitter
• Google+

• Status.net (PHP, OStatus)
• Diaspora (Ruby on Rails, protocol??)
• Buddycloud (PHP, XMPP)
• Friendika (PHP, OStatus)
• lorea.cc (PHP, Elgg + OStatus)

Conversation protocol not only API usage

• http://ostatus.org (v1.0)
  • Activity Streams
  • PubSubHubbub
  • Salmon
  • Webfinger
• OStatus (v1.1?, 1.5?, 2.0?)
  • Limited distribution („privacy“)
  • Activity Streams JSON
  • Conversation tracking
  • Remote site UI

• in use by friendika: DFRN, but „over-engineered“
• RINO node-node message encryption
• in development

I'm totally buggered from spending weeks and many late nights reverse engineering the Diaspora "open protocol" which is neither open nor documented - and all the existing documentation is wrong or incomplete. I get flak every day from Diasporans for trying to break down their freaking wall of silence and undocumented code and I'm a bit touchy about it.
