This came up over the weekend when a friend of mine was talking about the forum poster quality here on Fallen Enchantress versus your normal "game site" forum.  The question was, why is the "signal to noise ratio" so good here?

As some of you are aware, we barely moderate. I can't remember the last non-spam account we banned. Locking a post is so rare that it's a big deal when we do it. 

So my question to you guys, especially those of you who are on lots of game sites, why is the discussion quality so high (or if you disagree, put that in as well).

Thanks!
