"AskWiki, developed in partnership between AskMeNow and the Wikimedia Foundation, is a preliminary integration of a semantic search engine that seeks to provide specific answers to questions using information from Wikipedia articles. The engine is still in early stage development and has been designed to foster community involvement to help improve the search service and interface over the development period."
I've already asked it several questions and for the most part, have received relevant answers in return. My favorite being the question, "Why do birds suddenly appear every time you are near?" Which is not in the least a business question, but it sure did give me a smile.
