3 Google Wave Invites, Who Wants Them?

Have you found a good use for Google Wave yet? Until more people join (and there's some other way to be notified of a new wave without having to log in), I have a feeling I won't be using it too often. But, I've got 3 Google Wave invites to hand out. If you want to see what the much hyped service is about yourself, now's your chance. First three to comment get the wave invites!
