I'm going to pivot my answer: it's not <i>the best thing</i> I've found on HN, it's <i>how I use HN to find things</i>.<p>- Ask questions about things you're unsure of, even if it's just TLAs.[1] I also like to ask for references, and those can occasionally be real gems.<p>- Respond to others. Especially, respond in a "yes, and..." rather than a "no, but ..." style, where that's possible.<p>- Avoid tendentious arguments. I'll point out corrections, but try to keep those short where possible.[2] Changing minds is ... difficult at best. Leaving clues for other readers may have value.<p>- Skip the main page and hit the lists: <<a href="https://news.ycombinator.com/lists">https://news.ycombinator.com/lists</a>>. "Best", "Invited", and "Pool" especially are worth exploring.<p>- If you find someone interesting, check to see what they've submitted. Often individual's submissions are interesting curations of their own, though often these fail to survive the HN queue.<p>- <i>Use search.</i> I rely on HN somewhat to search terms or individuals of interest, and to look for commentary on articles I turn up to see if there's any illuminating relevant discussion (especially older articles). This isn't always successful, but it's virtually always worth the effort, particularly using DuckDuckGo's !bang search capability: "!hn <search terms>". A blank search with a date range serves as a "best of day/week/month/year" feature (see comment below).<p>- Try to read the article first, or at least <i>early</i> in your perusal of the comments thread. Comments ... often ... deviate from and/or are only very vaguely grounded in the article itself.<p>- There are a lot of people shooting from the hip. There are also some absolute domain experts and Internet legends who drop by. It's quite an eclectic crowd, though the gems may be well hidden.<p>- You can read an individual's comments and posts from their profile. Reading the dang's (HN's moderator) comments is a good way to familiarise yourself with HN's culture and norms: <<a href="https://news.ycombinator.com/threads?id=dang">https://news.ycombinator.com/threads?id=dang</a>> You can also email mods (hn@ycombinator.com) with questions or concerns about the site and/or your account and activity.<p>- Karma and votes count for far less than you'd think, though they tend to filter out obvious crud pretty well.<p>If you're interested in things I've found interesting on HN, I've favourited far too many submissions. There might be some gems (and embarrassments) amongst those: <<a href="https://news.ycombinator.com/favorites?id=dredmorbius">https://news.ycombinator.com/favorites?id=dredmorbius</a>><p>I've also been looking at HN's historical front-page activity and have a sense of the topics which are most covered (based on classifying the submitted site). The top 20 (+ "UNCLASSIFIED") of those represent 97.6% of all front-page posts, and are:<p><pre><code> Class Stories Votes (mean) Comments (mean)
