Thanks for taking the time to respond and detailing your take on my initial comment. Commenting as I did early in the thread was deliberate because of what I've observed in threads. I agree with your take that thoughtful comments tend to come later and can rise to the top. Another behavior I've observed is that an early hot comment can stick at the top, acting as a defacto root and coloring the resulting discussion.

I also think that one of the reasons for low-quality comments is due to people reacting reflexively and emotionally rather than reflectively and thoughtfully, and the intent of my comment is to remind people to take a beat before commenting. It's not motivated by the idea that the commenters are "bad" in some way, or to insult them. I get caught up often as well: I've certainly written posts that I then decide not to submit, or delete soon after submitting. As mentioned above, it takes effort to do this, but I think that many people do want to comment well and constructively, and that for many a reminder is useful.

One of my goals here is to minimize the initial period of low-quality comments and hopefully quiet the more heated subthreads. My comment wasn't a response to the comments that were already there: I hoped to get in early enough that those early commenters might see my comment and reflect a bit before posting something thoughtless and incendiary. I understand that this isn't going to stop all low-effort/low-quality/less-thoughtful comments. If we can shift the default towards more reflection, I think this can have a net positive effect on discussion quality overall, as well as perhaps encourage people to refrain from responding to the less-thoughtful comments, or responding in a way that can guide the discussion back on track. I know this isn't a novel idea, and it might be fruitless.

(As an aside, I had read this particular op-ed before it had been submitted to HN. I think it has some interesting points, and some that I disagree with, which is fine, and could be improved, but it is one worth discussing. I thought about submitting it, but had a pretty good idea of how the discussion would go on HN and decided not to.)

I think my thinking is consistent with how you understand threads like this work. Would you agree? Perhaps one difference between your position and mine is whether or not we can do anything to improve the sutation. Like you, I have a lot of respect and admiration for the work 'dang and 'sctb have done in moderating HN. Whatever quality has been maintained here is in part due to their efforts and those in the community who respect the place HN is. One point I do disagree on is the utility of low-quality comments. I'm glad you can see some positive effect from them. I'm a bit chagrined that you felt my initial comment was of that variety, but admit that it might have been better. The few times I've attempted this type of comment before have been longer, and I can see how "It would be really amazing if" can be read uncharitably. It reiterates to me the importance of the effort of all participants in communication.

You mention in another comment "This thread would seem to be a counter-example." Do you think our discussion may have played a role in that? It's impossible to ascertain this definitively, of course, and I chose the word "may" deliberately. Perhaps a better posing of this question is do you think discussions of the kind we're having could play such role? If you think it's possible, what is a better way to craft such a comment?
