@evan I am well aware of what that means, thank you.
I agree that XMPP had (and continues to have) a bunch of problems, in no small aprt related to the XEP compatibility matrix insanity — which to be fair they are now finally trying to reign in.
And I am not saying GTalk leaving "cased problems with the network", which sounds like implying *technical* problems. I am saying XMPP was basically mined for user base and techies' goodwill.
