I was searching for a website I had visited some weeks ago in Google but no matter what I searched for I got a page of irrelevant ads and equally non suitable urls. In the end I gave up and went to Bing and after just a few tries I found the site I was looking for.
I find myself using Bing more and more for search, the results are simply less cluttered.
At the moment I am advertising less on Bing, not because I want to do less but because I fixed the same fairly tightly targeted keywords on exact match on both Google and Bing and at the moment Google provides more results against that restrictive set of rules.
Last year I was more broad match on Bing and brought in 3 times more visitors, but there was wastage.
However I don't rank organically on Bing, pages that do well on Google don't rank on BIng others also don't, I have read about this but nothing seems to hit the nail on the head. We just don't rank there.
Anyhow, just to say, I like Bing more and more. If I could get to rank I would love it!
