The New York Post sez yes. The Post, in their usual overwrought style, claimed that Google was so surprised that Bing was actually good that co-founder Sergey Brin is actually taking a desperate hands-on approach to making improvements to the engine. Yeah. Sure.
But is it just marketing? Despite Bing’s solid search, really, it may just have killer marketing. Larry Dignan of ZDNet argues that Google is just search when sites like Bing and Wolfram|Alpha are actively offering more than that. A new branding approach may be key for Google. source
