Google Wave Invitations
I've been using Google Wave for a while now and they were kind enough to send some invitations for me to distribute around. So, I have 3 left. If you want one, just leave a comment here or send a reply/DM on Twitter with your e-mail address.
Geek alert: I'll be using FIFO as the sorting protocol in case there are more candidates the number of invitations. Good luck :-)
