A CNet article quoting the New York Post quoting an anonymous source who says "Bing seems to be of particular interest to Sergey" (emphasis mine). Quite a dubious chain of trust to back up such a mundane point. On the other hand, I don't think the headline "Does Microsoft's Bing have Google running scared? We have no idea" would not have worked very well.
