Hacker News Site Guidelines
Perhaps it could be added that submitters shouldn't submit "flamebait" - eg. titles/articles that will elicit very predictable, emotionally charged responses, or have borderline lying titles. In short, not tabloid material; which some other democratic news sites are buried in now.This is provably the most popular content for the masses, so it's something to watch out for. The editors here do already kill it and that's great, but why not put this guideline in writing?
