Yesterday, I watched the counter at Skeptics @ Area51 go from "The site's Public Beta will begin in 4 minutes", to "The site's Public Beta will begin soon", which is the status it's been in since.
What's the process for a site to reach public beta? Is there some automation, or does somebody make an objective call as to when the site is ready for it?
I don't really mind either way, I just thought the "4 minutes" thingy seemed to imply a very high precision, that it turns out didn't exist at all.
