Now, if one of you geniuses has an idea what actually went wrong I'll be very impressed.

I think Aardvark is a promising idea and could turn out to be very useful. That said, I'm wondering if the service needs a way for users to rate the quality of answers to filter out the people who don't really know what they're talking about (I asked a question about philosophy and got a rather wishy-washy response from someone claiming to be a Ph.D. student specializing in computer ethics).

I have also answered questions myself and Aardvark promises to only send you a couple every day.

I'm giving Aardvark a provisional rating of 4 out of 5 -- provisional because experience may well prove that the service to be more powerful than I'm giving it credit for.
