I honestly can't tell if your comment is snark or some type of realistic actionable advice.

If you intended actionable, what exactly do you propose SO to do to not be "high-traffic"? One of the meta threads say they got ~12k questions a day. (Most of them bad.) Should SO set a limit of 500 questions and after that, each person gets an error on the webform saying "Sorry, we've reached our max question limit today. We want to stay a low-traffic site so hope you'll understand!"

To recap some SO history from Atwood's posts...

2008 - StackOverflow is opened

2010 - Atwood and others notice they're getting inundated with too many bad questions. At this time downvoting questions cost karma.

2011 - To counteract the high volume of low-quality questions, they made downvoting questions free to remove friction.[1] Atwood noticed that users were too restrained in downvoting the questions and didn't exercise that power enough to clean up the site. Therefore, forcing the downvotes to have comments (add friction) is the opposite of what they were trying to solve in 2010 which was quickly suppressing the bad questions. SO has more traffic now in 2019 than back in 2011.

Perhaps some that are suggesting the idea of forced downvote explanations (I admit that it sounds like a wonderful feedback mechanism) -- don't know of SO's scale and the problems they had in 2010? I dunno.

[1] Jeff Atwood announced change of policy -- "Downvotes on questions no longer cost the casting user 1 reputation, so they are effectively “free”. [...] So, it’s imperative the question list have a high signal-to-noise ratio, and removing the penalty for those users who do take the time to read a question and later find it to be useless so they can down-vote is conducive to that." -- excerpt from : https://stackoverflow.blog/2011/06/13/optimizing-for-pearls-...
