Everyone's An Expert (at something)

A chatterbot, if you don't know, is an automated piece of software that responds to inqueries in a simulated conversational way. Think Joshua from Wargames. Many of these 'bots' provide answers to questions, while some are more on the novelty-side (like the now-defunct PalinSpeak).

Robots are cool, really cool. But they don't have all the answers. That's where Aardvark comes in. Aardvark works either via email or an instant messaging program (Google Talk, AIM, Windows Messenger). When a member signs up, they are asked to submit a few areas in which they have knowledge. When someone asks a question, it is automatically sent to those people who have knowledge in that area. The result is basically a big throbbing human brain.
