Facebook recently launched Groups for Schools, a new community feature that lets people create groups exclusively for other people in their university. This is a return to the time when Facebook used to be exclusively for students at universities, though now its just a small feature of an 800-million person network. However, it has a lot of potential. It is often difficult for college students to find other people in their major or get information about certain classes. This will become much easier, assuming enough students sign up for the relevant groups. It will also be able to be used as a classifieds site for rides, roommates, textbooks and more. In a later post I'll provide some more details.
