I don’t think the post count means much. In my case, I probably make 15 posts in the fluffier forums for every one in GQ or GD. The number of posts shows very little and post per day simply show that some of us spend too much time here and enjoy it too much. This is my only active message board and my only internet gaming location at this point.
To choose one of your numbers, I think it varies but I personally qualify closest to #3.
BTW: ivan is one of the few posters in my range of posts per day.
