"Google Co-op" is a community of organizations, businesses, and individuals working together to help improve Google search. The benefit to you as a Google user is new ways to quickly refine your searches to find what you’re looking for more quickly. Check out the Google Co-op directory for a list of providers who have contributed labels and subscribed links that you can add to your Google search results."

To subscribe to one of the providers, check out the co-op directory. I noticed digg.com was one of the providers, so I subscribed to them. Let’s see what happens…ah, I get special results at the top of search results page, where the sponsored links normally are. My search query…and how many diggs! Sweet!
