I hate Bing.
If it worked nearly as well as Google I wouldn't mind then cramming it down our throats so much.
I guess I'm so used to getting relevant stuff right away that I'm kind of spoiled.
For some reason I used bing for a while... I think I accidentally clicked it on my FF search box. Honestly, it was about as good as google, but they crapped it up with the big weird background images.
