On balance, in my view, given the growth that has already occurred for B77, it would benefit from becoming open as soon as possible. I think as things stand right now, the cat is already out of the bag if people are looking for a very small community where people can post without fear of what they say going beyond that community. I suspect that threshold was passed well before I arrived on the scene here. At this point, other than the lingering issues with TORC, there does not appear to be any central theme to B77 -- other than a place for a bunch of people who know each other already or who have friends who know each other already can come together to chat -- that would tend to attract large numbers of "outsiders" to this place if it were to be made open. So, were B77 to open, we would probably see a bit of a flood at first from TORCers coming to see what the story is. Some would fit right in and enrich our community, others would take a sniff and move on, and a few would linger for a while to continue the B77 vs. TORC battles, but that too would fade under the sunshine policy of B77 (vs. the "let's bury the bastards" policy of TORC). After that, B77 would experience the drifters who poke their noses in, then either stick because there's a fit or move in because there's not. That's pretty much the experience I had with one of the fragments of the old Ringbearer messageboards that went on for a good 2-3 years after the disintegration with a simple core of people, ocassional additions and subtractions occurring from time to time, all in a completely open and un-modded atmosphere.
For those seeking to re-create the small private community where they can speak in an entirely unguarded manner, the practical reality may be that they need to make another pioneering attempt at creating a separate space for that community and keep tight reins on who can join. I'm not suggesting this in any way as an invite for those people to move on from here, as I think they could (subject to the next sentence) very easily participate both in that private community and in the rapidly evolving B77 community. However (hint hint -- this is that "next sentence"), the creation of this private community will of course potentially raise some of the hard feelings that some over at TORC have (or feign to have) about the invitation-only nature of B77. I, for one, am not bothered in the least by the fact that my friends may choose to spend part of their time in circles that I am not part of -- after all, if they were constantly exposed to me, they would grow even more sick of me than they already probably are!!!
Those are my two cents.
