Do they speak English in What?
Wolfram Alpha is new type of search engine that's...well, sort of like the Google for information, rather than web pages. It attempts to take natural questions and return meaningful information about the question. For example, it gives you all sorts of cool statistics about names. You can find out how much an iPod will cost in New York. Or you can get a lot of information on math formulae.
But like most new technology, its best use seems to be f*cking around.
