But here's a curiosity: why are you here, then? What do you derive from reading all the comments from people that are by default wrong? Isn't it a massive waste of your time to read large number of comments, just to occasionally find one that you agree with as being correct?
When it comes to education (my field), HN is generally very, very similar to any other large online group such as facebook or reddit - the biases and areas of ignorance are the same.
So, in other words, I come here to read and learn about the things this site should know about - technology and related fields. Whereas comment sections such as this one, I consume much the same as 'opinion articles'.
But I do find HN useful in terms of randomly coming across topics that may be of tangential use in my work. Also, it tends to have more discussions that I'm interested in if I just want to blow off some steam on a forum and tends to have less vitriol than, say, a sub-Reddit
Maybe it's due to my approach to HN comments: if I find something interesting, I read, upvote and dive further into the thread; sometimes I comment. Otherwise, I move on.
