From the website:

If you love high quality reviews by great bloggers then you can find them through us. Why not write some reviews too?

Instead of expecting you to spend time and effort writing reviews for us, we're about your reviews on your blog building your reputation. We provide the tools that enable you to publish structured reviews to your blog (hReview for the techies out there) and we'll help everyone else to find your reviews, read them on your blog and then rate them and relate them to reviews by other bloggers. Our job is, above all, to be useful.
