More and more messenger-provider are supporting the jabber/XMPP protocoll. This is great for open standards, but I guess also it can create a problem for non tech savy users. Who the hell knows that his GTalk, GMX-Chat, Facebook-Chat ... account in reality is Jabber/XMPP-based.
While I understand now(I had filed such a wish earlier) that it is not possible to offer seperate account-configurations for all these Jabber/XMPP-based-providers, I see the urge to find a way to make the configuration intuitive.
For one thing I would suggest to keep a list of configurations via "Get Hot New Stuff" which has the several variations of how the username and other parts of the configuration is named and should look like. 
My other suggestion is to rebrand jabber/xmpp-support in way so that non-tech-savy users who do not find there messenger in the list choose jabber/xmpp. I do not know how exactly this should look like, but something in the direction of "Other, Standard-Messengers (Jabber)" or may be something totally different like a field, where people (independ of the protocoll) type the name of the service (of course with autocomplete)
Sorry for not having a more clearer vision of how it should look like. The only thing I really know is that its a problem right now. I have done quite a few Linux installations for some friends of mine. I always let them do some part of their desktop-configuration, because they have to learn it for themselves. The ones using Gtalk, GMX got stuck there, not knowing what to do. It would be great if this could be improved.
