There are no ads, and as far as I know, no revenue streams. This place was built community-and-discussion-first. Let me add: I don't think that mk should necessarily swear-off making money from this website. It's a time-consuming and costly endeavor, and if it keeps growing, would eat into more and more of his time, and I would like to see him rewarded. I just don't think it was ever a stated goal from the owner or admins.
Insom just answered this somewhere, but you're right, -it's not. The goal is simply to sustain a place for thoughtful discussion on the web. It isn't even necessarily to grow the user base if that means harming that goal. Not to put words in your mouth insomniasexx...I just don't think it was ever a stated goal from the owner or admins.
