Widget for collecting site ratings

Here's a new web widget--Mochimention. Mochimention allows any website to add user ratings to its website. There's apparently plans to add some form of e-commerce based on ratings. I'm not sure how good their product is since I'm not ready to try this, but the idea is a great one.
