I already brought this up in the Junk Drawer, though not too much happened from that discussion, so I'll bring it up here.
Are there too many users here?
I don't have much experience with sites in private beta, but I do know that I joined WorldBuilding in public beta, and got the UID 2072. This site is five days into private beta, and the newest user at time of posting has the UID 1271 (see here for the newest new users).
To me, it feels like private beta might perhaps be made more private, with numbers somehow closer to the number of committers (218).
....I wouldn't bring this up if I didn't think it was a problem -- I think it's going to be very hard (it already is very hard) to maintain standards of quality and on-topicness if we have six times the number of users who committed to the site*, traipsing in here and asking any question they think is on-topic, and all of them having close/reopen vote powers might make things very messy very quickly.
This post was partially inspired when I saw someone make the point that "...these people did commit and agree to this earlier. If 3 of your qs are closed, you're doing something wrong." ....but most of the users here did not commit, and aren't hanging around Meta LH or the Junk Drawer....a lack of communication of what is acceptable here is making things difficult for those users who are trying very hard to build a viable site.
