Most commentators there are playing to the gallery rather than answering the questions. The size of the question subs actually makes it harder to get a good answer.
The best karma return per comment is not to craft a lengthy, thoughtful reply but to fire of a snappy one liner as fast as possible.
What I have written is also not inciteful or original. It has been well know for a long time and is pretty much a factor of sub size and the demographic spread of the user base (which skews young, cis, male and american).
I was so unbelievably sick of the rote comments (bAnAnA fOr ScAlE?!?), and edgelord opinions, and half-formed trains of thought that overlook a lot of the nuances of whatever is being discussed.
The trick is that people can talk however they like, but they cannot mandate that a particular comment rise to the top of a particular scoring scheme. If commentors and voters would both use discretion based on the magazine they are in... but that is a moot point bc that won't happen either.
Short of something like a separate voting scheme (was this comment (a) popular or (b) insightful? or maybe both types can be up/down-voted independently; but then you could sort by either one or the other), I think it will just continue to happen here, even if less overwhelming than on Reddit, due to both different audiences and scales of population.
