I don't know about 300 different posters in recent history. I have noticed the hit numbers have been going up. Used to be it was pretty good for a post to get 100 hits (reads). Now some are getting in the neighborhood of 200. Your first post has 173. Of course that isn't necessarily 173 different people. If I go back and reread it, that counts again. Still, looks you're in the 30%+ response ballpark. Pretty good, I'd say.
