Thanks for the feedback. I plan on adding other ways of signing-up to serve the folks without an FB account. Even if you don't have a lot of friends, you can still collect feedback and add badges, which will increase your score. The social aspect is just one component. Regarding fake reviews, I have a background in Spam and Abuse. I look forward to tackling the fake reviews/users. Unhelpful reviews will be ignored and removed. Regarding the algorithm, that will be continuously tweaked based on feedback.
