I think a lot of people are missing the point of WolframAlpha... it's a COMPUTATIONAL engine, not a search engine.
There's a big difference.
For instance, just type in "moon". It figured out where I was (within10 miles), and then calculated the lunar path for my physical location, as well as the celestial configuration for my sky.
And Douglas Adams fans can be rest assured that yes, he's covered as well.
