I have discovered a new search engine that is definitely worth a try, even if only for the novelty factor.
It's called Ask Jeeves, after the Jeeves and Wooster books, and it is a real language searcher.
So if you wanted to know where Area 51 is supposed to be (this came up at work yesterday), rather than typing "area 51" and then sorting through thousands of responses. You can ask "Where is Area 51?"
Ask Jeeves will bring back a series of links listed on pull down menus that fit on one page and you can pull from there. Jeeves also searches the major search engines as well.
Sometimes you get some odd and entertaining feedback, but you often get what your looking for.
BTW Area 51 is located (in theory) in Roswell New Mexico.
