iUofC.com is a community forum site created by students at UCalgary, offering a central off-campus student-managed place for students to share information about classes. It's currently a rather empty shell, with forums created for every class. As students find out about it, it's starting to slowly grow.
The thing that blows me away about this "web *.0" stuff is that students are willing to take on large scale efforts completely on their own. Set up an open wiki, and students create tons of pages about what's important to them. Open up a forum system, and they fill it with topics important to them. If these tools had been provided by The University, would students be interested? It's awesome that the students don't need to wait for The University - they can come up with solutions as effective (or moreso) on their own. Power to the people. Right on.
