I jumped on it... like I do with most Google stuff... but now I don't know what to do. I clicked everything that I can click and moved everything I could move... but I wasn't all that excited. I think that wave is geared toward the "community" experience. So...
If you would like an invitation to Google Wave, let me know. I have 18 invites remaining. I don't think they send you something right away, but according to them, "Google Wave is more fun when you have others to wave with..."
Leave your e-mail in the comments or e-mail me.
If you are already using Google Wave, wave me something or add me to your contacts!
