I'm going to have to disagree. I've been a moderator on several high volume forums and I can tell you this, on a site like this that is so divisive and cliquish, there's probably 50 lurkers to every poster with more than 20 posts. Most people simply don't have the time or inclination to post on a site where the patients run the asylum. Out of all the forums I've been associated with, these is easily the most hostile towards newbies or anybody else that is not part of the "in crowd."
I think ISL is even harsher on the newbies. That's the only site I've been banned from (so far).
