It is true though; the number of comments I see on HN directly responding to just the title of an article - even when their response has been rebutted by the article itself - is very high.
Most of such advice works quite well for people who don't need it. Especially for the people with low income, low social capital, poor health and low personal skills, much of the advice will be outright wrong. And for some accomplished ones, it will serve as an extra prod to shame the former:
"Well of course they are not successful, they don't follow what scientists say."
The question is: why don't they.
A few constructive negative comments are fine, but this...
I wish there was a community similar to HN but without the toxic negativity. :(
