Late last week Google started rolling out a new round of Wave invites to folks who were invited by the first 100,000 Wave users. That means that if you tried the dedicated Google Wave Invites web site and got lucky there, you've probably gotten your invite by now (or you will sometime soon).
All of the folks that I invited received their invites on Friday and Saturday, but interestingly, none of those new users are able to send out their own invitations. That probably means that the folks at Wave are busy putting out a lot of fires right now and aren't ready to open their doors to that kind of explosive growth of new users just yet, but if you made it in with their first round of invites, you should probably be getting your invite soon if you haven't already. If you did get one, let's hear about it in the comments.
