I'm really curious as to how search startups like this get funding. The search market is so polarized right now that only a couple sites (read Google and Microsoft) actually have any share. So you're either Google or Microsoft, or you get no revenue at all.

Are they showing the investors something radically new behind the scenes? Or are the investors simply ignorant of the market? Of the new search engines gone public so far (e.g. Cuil), it's pretty much been the same old "text box entry leading to a list of links" story, and invariably a flop.
