I'd rather read "it's in the article you didn't read" than pretty much anything else.

The ideal case of course is that there are only legit questions and discussion from people who actually read what they are talking about. If they miss something that's fine as long as it's the honest exception. But this is not a thing that exists or can exist, so it doesn't count. It's not actually available to be a "What I'd like the most."

The next-most ideal case is when someone talks about something they didn't read, that no one else responds at all. The noise is the minimum possible noise from the original source and it just gets ignored. This aslo is not a real thing, and so not up for consideration.

What's left is some flavore of "noise". This is not avoidable. it will exist and the only choices are what form and flavor it takes.

I think it is most conductive for everyone, the poster, the bystanders, everyone, including people who don't like "noise", is the obvious and natural response. That it's the obvious and natural response for a reason.

Low value and snark may be true but it's irrelevant. It's still the best most productive reaction. (Within reason, 500 of the same response to one comment isn't very interesting reading, but multiple of the same agreeing response does serve a purpose which serves us all.)

That's what I mean by "I'd rather read that than almost anything else."

There are are no better options that actually exist.

As for the hall monitor aspect, telling people they shouldn't say the obvious most applicable thing is also hall monitor.

All in all, I just find the argument sorta valid but weak.
