In the US. In desktop. Globally, and once you count mobile, it's negligible. After 9 years on the market, including multiple rebrandings, it's a lost cause.
Bing was more than just a "rebranding" of Live search. And another thing, it shook Google from complacency. Do you remember the spate of improvements that came on the heels of Bing, some copied directly from Bing like infinite scroll on the image search?
We are all better off with a Bing than without. I can comprehend literally zero harm caused by Bing. It's not like you can make a "but IE hurts developers" argument here.
Moreover, if 1/3 of desktop US traffic is of nominal value in your opinion, I think possibly you're jaded.
Yep, google was complacent until Bing showed up. Then google released instant results, improved its images and video results. Bing had a better version of initially). Competition is good.
Maybe it's just a bias on my part, but I don't see anyone using "Binging" as a word to look something up. I would like to see the #s more in depth. (How much of it is directed from Yahoo, and IE, etc)
