While no place is perfect, I think the HN community and moderators do a decent job of moderating threads and preventing flame wars while also supporting the sharing of different views.
With the rise of AI, there’s a noticeable uptick of bots attempting to submit articles and comments to HN. You rarely see this low-quality content make it to the front page. That’s a lot of thankless community work.
Submissions cannot be downvoted. Only comments can be downvoted.
Try to keep the comments neutralish or at least built a pool of good karma around your submissions first, and then work the comments.
Good luck.
