I would just evaluate your argument on my own and I would evaluate the counterargument in the comment on my own.
The precise issue is that a sizable fraction of the audience will predictably not do this, or will do it lazily or incorrectly.
On LessWrong, this shows up in voting patterns, for example, a controversial post will sometimes get some initial upvotes and then the karma / trend will swing around based on the comments and who had the last word. Or, a long back-and-forth ends up getting far fewer votes (and presumably, eyeballs) than the top-level post / comment.
My impression is that most authors aren’t that sensitive to karma per se but they are sensitive to a mental model of the audience that this swinging implies, namely that many onlookers are letting the author and their interlocutor(s) do their thinking for them, with varying levels of attention span, and where “highly upvoted” is often a proxy for “onlookers believe this is worth responding to (but won’t necessarily read the response)”. So responding often feels both high stakes and unrewarding for someone who cares about communicating something to their audience as a whole.
Anyway, I like Duncan’s post as a way of making the point about effort / implied obligation to both onlookers and interlocutors, but something else that might help is some kind of guide / reminder / explanation about principles of being a good / high-effort onlooker.
