This reminds me of Stumbleupon[1] from back in 2005-ish. I used to love using it before they decided to pivot and remove all of the things that made it great.
Additionally, reviews led to discovery of people with shared interests, when I saw the same people liking, sharing and commenting on stuff I liked. Following these people then added another layer of filtering to my ^stumbles^.
Might be food for thought.
I'm actually just starting to implement features like these. If you make an account then go the the Account tab, you can enable a public profile like this[1]. So far I'm planning to add follow/subscribe, commentary (i.e. comment on items instead of just rating them), and showing users who've rated the same items as you.
