At this point what we need is a complete revamp of the site as a whole, including moderation policies and moderator engagement. I'd like to see the community representatives engage more with the community here. We're not a terrible lot, really - yet the bulk of their time is spent on Twitter and Facebook. Ironically, a quick look at the comments in reply to posts over on those two sites will show that the moderation isn't as intensive over there and that the comments made are often far nastier than any you find over here.
