Horses for courses
Just a thought but ... ... is it reasonable to consider one skin for those namespaces where the pages already serve a role resembling a social networking function? e.g.
 * Blog:
 * Forum:
 * Talk:
 * User:

and a different skin for the content focused pages within such namespaces as
 * Main:
 * Category:
 * File:
 * Help:
 * MediaWiki:
 * Template:

Content is paramount in one context (the purist/traditional wiki context) whereas Contributor is perhaps more important in the social networking context.

I'd be less disappointed by ads, attribution and avatars consuming screen space in the social networking areas if that is balanced by the complete absence of those features in the content areas. I think it is really a matter of relevance and context.

Toolbar come Adbar
Finally, some cynics might view an anchored toolbar as the harbinger for an anchored advertising bar. Let's not allow that camel to get it's head inside the tent.
