My personal feeling (with no bearing on present company) is that the rules hysteria sometimes gets a little out of hand, particularly on newer LLs. On my first LL I copied rules from everywhere else and tried to go into specific detail about every little thing I could imagine, to the point where I constantly had to consult my own rules while reviewing because I couldn't remember what they said.
On Quantum Porn I've taken a more
relaxed approach only setting down a few basic ground rules. Apart from that, if you build a nice site, try to make an honest sale, don't try do dick me or the surfer around, you'll get listed.
