One concern I'm trying to confirm, the new "Google Hangouts" (not to be confused with Google Hangouts from 2012) seems to be rolling up Google Talk, and Google+ Messenger. And Hangouts is not XMPP (Jabber) based.

I use two IM networks still, AIM and XMPP access to Google Talk/Google+ Messenger. I dropped MSN a while back, and it's now dead anyhow integrated into Skype. If XMPP is really going away at Google, Trillian/Adium/iChat and other multi protocol programs become less useful now. Not sure what I'm going to do there going forward.
