Ever wonder who would win in a fight, Superman or the Incredible Hulk? Well, Flickr Fight certainly won't tell you. But the site will let you know which superhero is more popular on Flickr, and isn't that just as useful?

In a nutshell, Flickr Fight lets you enter two search terms. The web service will then go to work tracking down all the Flickr images tagged with those terms. The keywords with the most images wins. Using this highly scientific method we were able to determine that Ubuntu beats Gentoo; Windows Vista beats Windows XP; Windows beats Mac, while mac beats PC; and as you probably guessed, Superman kicks the Incredible Hulk in the behind.
