Odd, I got one Gmail invite today. What happened to my normal six every day? I see two possibilities. First, Google may have decided that they have beta users for now (which would make sense considering the problems they had a few days ago) and are going back to the previous rate of invites. The other possibility, which I just realized is very similar, is that one of my invites expired because it wasn't redeemed, so Google gave me another. The invite came in the middle of the day, which supports the second theory. Maybe I'll get six more tonight. I'll keep you posted ;).
