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.
Wow, and when I thought on putting a poll in this, the first option was going to be 1000. Guess I was wrong...
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.
Depends what you mean by active - Everyday for an hour or more I would say maybe 3/400. People who log in at least once a week I would go anything up to 5k. It is hard to tell there is a hardcore of about 50 who seem to be here all the time and they distort perception.
