I'm really curious as to how this is different than Bing using google's search results in some form of aggregate pageranking. If we assume that some arbitrary metric of "authenticity" exists for searches and a search for mbzrxpgjys results in results in a low (<0.1%) result for authenticity, but Google suddenly declares that www.page.com is the foremost authority in mbzrxpgjys's, it stands to reason that a good page-ranking scheme would take that into account and bump it to the front of the line.

I don't think it's cheating, no where in the article does it claim that they aren't doing their own search, they are just using Google's results as part of their own search algorithm. Is that really such a crime?
