I guess I could have tagged this on to the other discussion, but it was getting long and I was losing track of it. Anyway, the long and short of this is, I have 8 Google Wave invites if anyone is interested. Reply with an email address, or add me as a colleague and message me your email if you are interested. First come first served. I only have 8 invites.
I think there are enough out there now. I have a number undistributed too. There have been a few opportunities to use it since the Classroom 2.0 crowd swarmed Google Wave for a first look. None of them have proceeded much past chatting. That can be done on other platforms with equal or greater ease. I am still waiting for a truly collaborative moment where something useful is collectively created in a wave.
