With the race for the Democratic presidential nomination entering the homestretch, more and more people are talking about superdelegates, who may be crucial in determining whether the party's choice will be Hillary Clinton or Barack Obama. But what are these superdelegates? Who gets to be one? Are you as confused about them as I am?

Rick Klau, an employee at Google, took on a personal project to help clarify things. He set up SuperDelegates.org, a wiki-style Web site that not only tells you how the Democratic Party's superdelegate system was developed, but also lists who all 795 of them are and whether or not they've pledged their vote to Clinton or Obama. Even cooler, Klau has done an overlay on Google Maps, so you can see where they're from and whether they're still undecided or are leaning toward one of the candidates. Check it out here.
