The area51 Faq at http://area51.stackexchange.com/faq (which I believe to be relevant for dba.stackexchange.com) states that a "site is launched for a beta period to seed it with questions, develop the FAQ, appoint temporary moderators, and refine its design."
I was wondering how it is determined how long this period lasts, and how far we are from the end of it.
On a related note: Is this site ready to leave private beta? meantions a private beta. Is the private beta just the same as the beta, or is there something like a public beta (and which one would this site be in?)
