Bing? Nope, their marketing sucks. Their product is behind in terms of tech. They have absolutely no direction other than if it's out there people will use it. Everyone in their marketing department should be fired, there's zero creativity to compete with Google.
That's the problem, they are with Microsoft, there's endless amounts of $$$$, it's at a point where throwing money at it makes the problem "pretend" to go away. They'll never get over that. They also have the IE/new computers, devices, etc. so they rely on that. They need to stop relying on their $ and forced tech on devices and start marketing correctly, and doing the right creative products.
And unless Google has a serious, serious screw up that Bing can tout from, they aren't going to ever compete on a higher level.. The whole company is a fail in my book, no creativity direction in the online industry equals poor performance.
