www.cinemablend.com/ -Dark background colors
www.digitaltrends.com/ -Dark background colors
technorati.com/ -Dark background colors + ads above fold
www.daniweb.com/ -Dark background colors + thin pages
On some of these, I don't consider them "dark" background colors. Some have blue or green headers, but many of the pages have white backgrounds (like Technorati) and cinemablend.com has a nice orange background. I have a site that soared during panda, and it has a very dark blue header and a blue background. Only the content area has a white background.
Some of the other examples that have black backgrounds may be playing a role. Perhaps it's "certain" colors that are a turnoff? I agree that many of these examples also have ad banners sitting at the very top of the page (turnoff). Many of them also have sitewide navigational menus with dropdowns (I don't see the problem with them, but it has been speculated before that it may be a negative).
