It's funny and sad that XMPP hits almost all of the points, has been around since 1999 and yet every year someone reinvents the wheel and makes another messenger system. There are what, about 60+ by now.
Granted XMPP is not a messenger it's a protocol and a bunch of standards but still it's hard not to laugh.
