Except - if you are working on a project and Soshiku has a Facebook app you can just add your classmates to it and have communication be central and clear.

Unlike the real world where you often call one person and that person calls another person in the group and so on. Where there is no central repository for sharing links/resources for the school assignment.

Soshiku has a great design and fills a sizable need in my opinion, getting schoolwork done. I for one, probably would have used it in high school.
