Aardvark, the question and answer service that was later bought by Google, initially routed and answered all user questions from their internal team.

Can imagine that :) I wonder how many of Quora's initial questions were internally answered too?

Aardvark was a nice service, both for finding answers (a well-managed online "word of mouth" service), and for finding surprising intersections in interests with your acquaintances.
