Here's an open-ended question for all of you. I saw the recent thread on the main page about "honeypot" submissions, including a comment by pg, the site founder, that the quality of comments on Hacker News has declined. What can I do about that? What can we all do about that? What voluntary cooperation can we engage in as users of Hacker News to make HN a more useful, friendly, and informative online community? I invite open discussion of this issue here, with any and all suggestions welcome, including suggestions directed specifically to my own online behavior.
One suggestion I have made before is actively to upvote comments that either 1) ask for follow-ups with more details or facts to clarify or back-up a parent comment's statements, or 2) provide asked-for details or facts (especially with links to reliable online sources or citations to dead-tree reliable sources). I also like to silently upvote comments in which users are polite and say "please" or "thank you," as a measure to promote civility. What else is good to upvote? How else besides upvoting good comments and asking follow-up questions can each user here promote better comments?
Thank you for any ideas you share here. And many thanks, of course, to the dozens of users here whose posts and comments make HN a valuable community to me and to other users.
