Very interesting experiment by Packard Foundation to create a '"see through"filing cabinet' wiki open to the world.
What would be the benefit to a class or school or educational nonprofit doing something like this?
Curt Bonk is an amazing instructional design professor at Indiana University. Here he has 27 videos (about 10 minutes long each) covering everything from discussion forums (I learned a lot!) to Blended Learning to wiki uses and applications. All free!
