It's a little bit quirky at first, but I think in the long run it'll clean up nicely. Once people get the hang of writing actual reviews, you can just click on the reviews link so you're not hunting things down. I can add categories and whatnot down the road if need be. I had initially set it up with a few categories, but things like the thumbnails for the reviewed item aren't working. Something to look into as I have time.
I just hope it's worthwhile to folks and helps clean up some clutter from the review section. Having categories to filter what you're looking for will go a long way I think?
