Before purchasing something, it's always a good idea that we read other users' reviews and see what they have to say about it. We'll then have a better understanding of what the pros and cons of the product are. Built on Rails, Let's Review is a site where users can read others' reviews, or write their own. Anything can be reviewed, whether it be a restaurant, a book or a movie.

I think this project has potential. For instance, the site can easily feed its content (mostly reviews) to retailer sites thanks to RoR's XML support.
