I still kinda wonder if they saw the success of the invite system for gmail (I remember a lot of late nights begging for an invite on various forums) and thought that it would work again.
The critical difference is gmail still worked just fine with hotmail, yahoo mail, aol, etc. Wave was useless if both sides didn't have it.
