What the hell? I just checked my account recently, and I had 50 invitations ... Last time I checked (a weekish ago), I had 4.

How exactly do you get them?

Heh.. Someone invites you. Duh.


Just joking..

My friends and I have all gotten that too. My guess is that Google is probably about to go public with it, but I don't work for them or anything, so don't take my word for it.
