Well, look at it this way. The 1000 post average that you just calculated is the bare minimum never of posts NS gets per day. NS has grown to 20 times it's original size in a short 4 yr period. So, that means there were probably WAY less posts in the first year or two, and WAY more posts recently (when there are probably close to 1500 unique members visiting per day). I suspect the post per day is closer to 3 or 4000.
