Forum usage ebbs and flows. Unless this place becomes tumbleweeds, I’m not too concerned. Sure, some of the conversation has inevitably shifted to Facebook, but that only really works for immediacy. Facebook is a nightmare for ongoing conversation, deep threads, organisation, and search. Also – and most importantly – Facebook owns everything. You’re one hack or ban away from everything being gone forever. (And I should know. I admin a band page that very nearly lost everything through a spam bot attack.)
As for claims this is a horrible place, I’m not sure where they come from. I dip into Facebook reasonably often, and I don’t really see many comments along those lines on the official 2000 AD page. People are a mite grumpier in one of the groups I joined some time ago, but then half the time I wonder whether such things function specifically to gripe about everything 2000 AD and Rebellion are doing these days, having glued rose-tinted glasses to everyone’s faces.
On the nice or nasty, I will say that of the forums of any size I’ve moderated, this is by far the least hassle. We’ve had very few bans here, and those we have had got discussed at almost agonising lengths, usually over a period of days. It’s pretty rare that an admin/mod has to wade in and tell everyone to pipe down a bit.
