I ask this, because although I love it here, I thought this was loaded of people, and was expecting each question to have hundreds of answers, but I see fairly few answers and never bothered to check if it's always the same people or not.

I think it MUST be at least a few hundred. There's ~70 mods and I don't know all of them so there must be a reasonable group of posters to police to need that many mods.1

I think it's just the huge amount of answers that come through, and the fact that most of them have been asked 500 times before, discourages a lot of people who may otherwise be active from really answering all that much.2
