What is this new invite fashion? OK, it worked with Gmail, making it most attractive because invite-privileged. Darn, works once, after it gets annoying. I never beg, and I am fed up with these low-psychological behaviours. They can sit on it.

Yeah, it is getting rather annoying. I think people are doing it primarily because they can continue to roll it out to more and more users while tweaking performance. That way their server(s) don’t crash on their first day.
