TIME repurposes their pre-built online ratings system.

heads up: this is a pretty old post, it may be outdated.

TIME does an annual 'person of the year' story. As a part of their selection process, they allow online viewers to read a brief blurb about each of their candidates and rank them using a customized system. They also use the same interface for the TIME 100, and a few other various unofficial polls.

I'm very impressed by their most recent utilization though. They've taken the 'gaffes' of each of the political campaigns, allowed you to view them and then let you vote on how much they matter. It's pretty funny to see what the News Media has been focusing their coverage on.
