Looks to me in the areas I traverse Bing has had a recent update. It practically looks like if you are not a known brand you might have taken a licking. In some areas I look at they're overrun with keyword domains which seem to be the exception to the branding. The merging of so many variations of keywords also is slowing the long tail and giving particular advantage to the “big boys”. Also too many weak e-zine type sites saying nothing. Prior to this I thought Bing was improving via a healthy mix.
I have to agree they're drawing their results from a much a smaller pool of sites than Google and recognized that a while back. You really don't gain the status Bing is seeking and do things like that. I've seen dead search engines that had reached that level years ago.
Bing Update?
