I'm sure I've read it somewhere already, but I can't seem to find it now. Does StackExchange have a page where they have published the milestones required for a site to progress through its various development phases? How close are we to being out of Beta, and becoming a full-fledged site?
According to the Changes to Stack Exchange entry on the Stack Exchange Blog...
This phase will last between 60 and 90 days. At the end of that period, the site will need to reach a minimum critical mass to continue and move on to full citizenship.
