Feedback from Google:

“Dupont was noncommittal about whether the company planned to build in that feedback loop, either directly as a signal to influence search rankings or indirectly as extra data that could help the company judge the relevance of its search results. But he certainly didn’t rule the idea out. We don’t close any doors. We constantly evaluate signals” that are incorporated into the search results algorithm. Search is adapting to the Internet as it becomes a more participatory medium. Now you have people telling us specific things about how they’d like to see their search results.”

I guess it’s wait and see time. But seriously, how fun is it to mess with the organic results?!
