Looks like a great web site. There is/was a similar web site called ConceptFeedback (http://www.conceptfeedback.com/ http://www.conceptfeedback.com/) that I liked a couple of years ago, but then when they went to monetize the whole spirit of the site changed. I believe they started as a similar concept of feedback exchange, sprinkled with light gamification/badges. Anybody know the story behind it?
