Kosmix.com is a new startup that's trying to shake Google's dominance of the search market. Good luck with that, guys. However, I rather suspect that their real agenda, to take an analogy with politics, is more similar to the Green Party's approach to Labour and the Conservatives. It's trying to change things not by grabbing a majority share, but by innovating and passing popular ideas up to the people at the top.
Kosmix is trying to change search by providing context to your results. On the results page, you get a list of (Google's) search results, as well as relevant forum posts (from Omgili), Q&As (from Yahoo! Answers), Videos (from BlinkX, YouTube and Trueveo), Images (from Yahoo!) and News and Blogs (from MeeHive). There's other resources too, depending on what you search for.
