In light of the effort to improve HN, I 'd like to politely (and humbly) ask for some feedback. What can I do to make HN a better place? I'm not looking for feedback on specific comments (we have downvotes and relies for that), but general advice. Comment less? Be more technical? Be less arrogant? Be more polite? Stay on topic? Anything else? I have quite a few karma points, but I often say that moderation is most needed when something is popular but unhelpful to HN. In the same spirit, I am thinking that feedback is most helpful for people like me who have a lot of karma but could be even better HN citizens. Please? And thank you!
