A new search engine launched today. It's called Wikia Search and it's by the same guy that brought you Wikipedia. It's not a Google-killer, yet. But by allowing users to rate the results they get, and then pushing those responses back into the search engine, Jimmy Wales hopes to create a search engine as powerful and useful as the big G of the Intertubes. That's a tall mountain to climb, but it'll be fun to see how the hike to top goes.
