“Groovy Motherfucker”

Truly social search. Sign up and enter some of your topics of expertise. Then IM a question to Aardvark. It will forward it onto appropriate friends and friends-of-friends, and pass on any replies. My first test was completely successful.

I really like they way signing up to ask questions implicitly gets you on the hook for answering, as well as the fact that they link to your Facebook account to quickly garner a social graph. I have some invites if you want to play too.
