Because repetition is boring and the goal is interesting conversation rather than ensuring you don’t miss an interesting link. The interesting links are supposed to be a side effect of you engaging in or simply reading an interesting conversation. Summary comments, LLM output and prepared linkathons are discouraged for similar reasons, if the parallel helps at all.
Do you have any examples of “Summary comments, LLM output and prepared linkathons”? I’m not sure what a prepared linkathon is at all, and I wonder if the other two are as bad as you suggest, and maybe seeing it would help.
by "prepared linkathon" I mean specifically what that commenter was doing - you have a pre-made reply of N (for N >= 1) links that you keep spraying everywhere.
But I'm not sure what you mean by "as bad as you suggest". I wasn't suggesting a level of badness, more describing HN's messageboard goals, however aspirational.
Edit: and since we're exchanging questions, I'm curious what sorts of human interactions do you have in mind in which repeating the same thing 20-odd times is not considered, if not outright abusive, at least impolite and non-constructive. I can think of a couple - say, sports events or protests. But none of these map to 'nerd messageboard' in any meaningful way I can see.
Frankly what's worse is seeing such a magnitude of evidence to the contrary of popular discourse, yet being entirely unable to help bring context into the fray.
Instead, we get regurgitation of tired propaganda and heavily misleading narratives. If the world looks exceptionally confusing and chaotic, or if the world is fully of irrational boogeymen, that's just because you don't have the right perspective yet.
The geopolitics community knows the situation well, and doesn't look at Trump as a big scary orange man. They look at Trump as another American elite, who's been elected during a chaotic time in American society. You can also look up Jeffery Sachs (social democrat) who speaks at length about these issues.
I've mostly lost faith in the conversations on here. HN mostly is a competition about who can sound the most fancy. The actual content of the discussion has become tertiary. At this point, my only goal is to reach out to those who are open minded and haven't heard these other perspectives. To hell with internet points.
Well, that's an argument and you certainly can and should make it in response to whoever you are hoping to convince somewhere in the thread. Pasting the same URL at people is not 'discourse' or conversation, it's sloganeering. You can't do that while also decrying "regurgitation".
