Yeah, I had some thoughts a while back on one way this could work using social search: http://tchblg.wordpress.com/2008/05/31/why-friendfeed-deserves-a-one-billion-dollar-valuation/ http://tchblg.wordpress.com/2008/05/31/why-friendfeed-deserv... Basically, you'd get results back that are from conversations posted by your friends, side-by-side with traditional results from a search engine (using something like Yahoo's BOSS). Then, if you still didn't get the answer you are looking for, you can broadcast the original query out to your online contact list to see if anyone within your social network knows the answer. You wouldn't get instant results, but it would likely be a very good, trusted result. This probably works better for things like opinions (what's the best Chinese restaurant in Seattle?) vs. a fact-based search like "C# string replace". I would seriously avoid trying to take on Google or MS or Yahoo by trying to out-index them. Cuil has millions in the bank and some of the world's foremost experts in search at the helm, and things aren't looking all that bright so far. There are lots of problems to solve in the world and lots of approaches on how to solve them - solving search by out-indexing Google should probably be pretty darn low on your "problems to solve today" list.
