We have been happily and intensively using Google Wave over the past week and we are impressed with its promise and engineering.

Wave is a new way to collaborate online.  You can have conversations in
real time and you can share resources, files and information in
multiple waves with many different groups and people.

have used Blackboard and Basecamp in the past to teach online and we
find that — unlike the awful and disappointing Google Sites — Google
Wave is actually a fit solution and replacement for both Basecamp and
Blackboard at zero cost.

Google Wave’s
impending integration with Google Apps will make it the “go-to”
collaboration arena for business users and the quickly indispensable
collective mindshare application for students and educators everywhere.
