ShareYourScore.com is a site where you can upload your Windows Vista Experience Index assessment and share it with the world. You can also take a look at other people's top scores, and even see average scores for a particular component.

I'm hoping they expand the site's functionality in the future, but it's a good start. If you are unfamiliar with the Windows Experience Index, just open Control Panel, and type in performance into the search box. You should already see your score, calculated when you installed Vista for the first time. Once you've uploaded your score, they will even give you the html so that you can put the score as a badge on your own site:
