I wasn't thinking of it as a way to see who "contributes" more than others or anything like that, I just figured it would be a nice statistic to know.
another cool stat would be average words per post, or a word count instead of a post count.
One feature that is actually helpful that I would like to see: Another forum I visit used to have a feature that when you hovered over the post a popup box appeared with the first several sentences of the post. That forum had tons of posts so it was a nice way to see if the post was even worth taking the time to click on it. While this is a much smaller community I would still like to see that feature.
