Yeah, I kind of got excited about WA after using it for a few things, but I run across results like yours enough that I now use WA only for new variations of things I've successfully searched for before. It rocks when it rocks, but the rest of the time the coffee cup sounds well before TDC.
I mostly use WA to compare weather in areas and compare land mass. They had some interesting demos, but based on the hype I expected a better answer to "how many ping pong balls to fill a VW Bug"
