     Well, there's the Diaspora protocol:
     [2]https://wiki.diasporafoundation.org/Federation_protocol_overview
     And... StatusNet/OStatus, PumpIO, TentIO, ActivityStreams,
     BuddyCloud (XMPP-
     based, I guess), and quite a few others I don't really remember.
     Some of them
     are related, all are incompatible. And all the devs are showing
     strong
     symptoms of the NIH syndrome.
     Which is absurd.

   that indeed is stupid and so no one have solved it yet... for social
   network or basically any IM/chat/etc to be usable it must have majority
   of people (eg. your friends) users there, otherwise without people they
   are totally useless so currently we're stuck with no-so-great
   applications/protocols only because everyone already are on them like
   Facebook and Skype. On that mailing list there were discussion about a
   polyglot protocol/application which could support all networks so users
   wouldn't be forced to migrate which I think is essential because a lot
   of people won't bother. There was mention to [3]Sockethub which seems
   quite cool, only for a bit different use case I would say.
   Another thing I would like to mention is [4]BitlBee it is a gateway
   between various IM/chat networks and IRC so you can chat with friends
   on Facebook using your favorite IRC client, or post a tweet on your
   Twitter and use various other protocols. It even supports OTR.
