If you don't know, Yahoo opened up their search engine to developers (build your own search service, or BOSS (yes, i know it's not quite an acronym)). Anyway, someone has cobbled together a Cuil look alike that, according to TechCrunch, seems to work better than Cuil. From the article "And while Yuil isn’t really doing anything new with its search results, they’re more relevant than the occasionally bizarre ones we’ve been getting from Cuil."
