I used to jump straight into the comments here because that's what I did on FB/Twitter.
Using HN this way made me feel just as distracted, frazzled and upset as regular social media. Fortunately I've spent enough time here to know which topics tend to have useful information in the comments, and which ones are going to be a retread of stuff that's been discussed ad nauseam before, H1B visas for instance.
The average HN comment tends to be more civil and erudite than elsewhere, which I mistakenly conflated with being knowledgeable and open-minded. As it turns out, people can be just as stubborn and non-emphatic here as anywhere else.
To get the best out of HN, I always decide first if I'm going to read the article. If no, then I'll pass on the discussion as well.
