Matter of time before somebody does this. It will probably be one of the big boys, which will lend the project some trust and credibility.

"Google has outlined a concept for real-time online voting in the Google home page in a patent to the U.S. Patent and Trademark Office. Entitled 'Social Voting-Based Campaigns in Search', the application proposes a voting user interface (VUI) that will enable a user to submit one or more votes in a voting-based campaign, giving the hypothetical example of a campaign to vote for the 'Top American Singer', with users authenticated via Google log-ins. If implemented, the system would represent a new foray for Google into generating rather than recording analytics and metrics of popularity."
