Haven't they heard about IRC (RFCs 1459, 2810–2813)?

There seems to be this general assumption at the moment that a) XMPP is the only open chat protocol about and b) its dead, so everyone decides that the only logical course of action is to write and use custom proprietary protocol. This, of course, massively sucks from a UX perspective where I end up having 100s of identities and apps and logins that I use (semi-)regularly to not just chat with people, but also comment on articles, discuss things on mailing lists etc.
Edit: whoops, I had commented once before, it was just so long ago that I forgot about it!
That and the use of hashtags to group things together on Twitter, etc.
I guess it's just a "thing" now.
I deeply appreciate the history and communities available on IRC, but as a protocol, good riddance to it.

MSN Messenger's protocol was submitted to the ECMA in 1999, but MS made changes to their implementation almost immediately that were never documented.
