Speaking for myself, not Dan, but for non-technical topics that appear on HN, the discussion would be a lot better if the average commentator read the obvious Wikipedia article before commenting. That’s true even though Wikipedia has a lot of problems.
I have vague ideas of a forum, where any new poster has to answer some basic questions about the topic first correctly.
Most online discussions would probably benefit from that.
Incidentally, check out this wacky alien-looking worm that exhibits bioluminescence even though it lives its entire life inside of a tube, so there is no one to perceive it: https://en.wikipedia.org/wiki/Chaetopterus
If you see it in the front page and it bothers you enough to ask the question maybe you should try to find another community.
