Anyone get on Wave yet? I've got an account (but no invites).

The idea is cool, but it really falls short without anyone to use it with. I'm hoping once it launches fully I can get some other people at work on it so we can use it instead of email for certain things.

It looks neat but, yeah, seems pretty worthless if no one else is using it.  I could see this potentially being useful in a corporate environment if you could get everyone in an organization on board.
