Wouldn't that be good? I remember back in the day you could only get Gmail thru an invite, it was an awesome strategy. "Currently closed for applications" creates FOMO. They'd just need to actually get the GPUs in relatively short supply. They could do it in bursts though, right? "Now accepting applications for a short time."

I'm not an internet marketer but that sounds like a win win to me. People feel special, they get extra hype, and the service isn't broken.
