Some thoughts -I like the idea. I like where you're going with it. A way to draw users in - is a style similar to Buzzfeed. Create a content article (eg: for ladies, ones on shoes, or dresses... where you have attached scores). Share that on facebook, and share that on twitter to the respective groups, niches, etc. That could be a good way to draw people in. From a behaviours perspective, consider having the person first "make their verdict/review" and THEN create an account to save. Or even try anonymously at first. The reason.... people are more likely to register once they've made even a small investment of time (eg: star rating, review, etc) than they are 5 seconds earlier before the rating. I didn't see the use case initially as much of "I have an opinion, my friend's is different let's test". But what I did see, is something that could be viral easily (eg: similar to the Facebook "what kind of star wars character are you, etc). Your ratings incite opinions, which incite emotion. People act on emotion.
