  @ExAr I suspect your comment was downvoted to oblivion because people didn't realize you're the OP and thought you were an LLM summarizer bot :(

    The comment reads like an LLM summary. And we don’t typically get an OP summary on a new post. Just post it and let people read it.

      HN appears to encourage it, because it shows a text box which becomes a top level comment when you submit, although it isn't obvious that will happen.

        Huh, that definitely explains it. I wonder how many people know that. In that case it's particularly unfortunate to downvote the OP simply for filling a field in the submission form! Sigh… I guess it's another case of LLMs having made the world a little worse for everybody.

          I don’t think it’s because the comment was submitted. I think it’s because it reads like LLM output.

          Personally, I’ve only ever provided a summary if I felt the headline wasn’t clear enough.

    That's perfectly ok, they're using HN almost exclusively for promotion. See comment/submission history.

      But the articles are well-researched, very high quality (the illustrations in particular are incredible), and in every way prime HN material, and there's no money involved as far as I can see. I definitely don't have any qualms about self-promotion of this sort of stuff.
