Re: [Trisquel-users] How to date girls using free software :P

I only use Facebook to contact a few of my "legacy" friends from before I  
stopped using things like Facebook. Eventually I hope to convince those few  
of them to at least communicate via email or Jabber with me.

As far as I can tell, Facebook uses a closed-up, proprietary XMPP protocol  
for chat. It is a web standard after all. Of course this doesn't mean their  
chat is free: you can only talk to other FB users, and whatever's going on on  
their servers is obviously proprietary.
