The post count turned out pretty anti-intuitive, I would say. People who I thought were lurking actually aren't. People who I thought had solid contributions are a little on the low side.
My two biggest suspects are two of the top three posters (and the other is me). That worries me, since in a vacuum, scum aligned players write fewer posts than town-aligned players. However, people who come under suspicion end up posting more than others. So it's a bit of a catch-22.
I actually think each person needs to be evaluated critically in this regard, and not on a flat scale.
I don't know much about liopoil, so I don't know what "normal" is for him. But for Theorel, that is pretty spot on. Very few posts, tons of content in each.
For the Glooble's and Yuma's, they are actually just higher than I normally look, so I wouldn't consider them "lurking" to their own standard.
And this is the point I made about myself earlier. I HAVE been underposting. Yesterday because I was RL gaming, today because I've been swamped catching up here. My overall numbers might still be above average - but I'll be the first to admit that against my own standards of posting, yes, I am in fact "lurking".
Looking at that list, in all honesty, I think everybody is contributing at or above their normal levels. I see no real lurkers (besides myself) listed.
