Startup Idea : Social Network for school projects

When you're working in a group, not everyone always gives 100%. This app would change that by offering a review service for group members in group projects. Ideally, it would link to a school directory or Facebook account, and other students would be able to rate their members on different criteria such as attending meetings, completing work on time, working thoroughly, and communication. It could offer constructive criticism that only the recipient could see. The app could go in one of two directions: either a public directory so you could see who you want to work with (like a ratemyprofessors.com) or it could be solely for review and improving future group work based on feedback and criticism. It could also be used by teachers to get feedback on how individual members worked, which most teachers already do when the project is completed.
