HN is so much of a echo chamber lately for some topics, there was a recent discussion about FB head of integrity leaving the company and the top comment and thread was a personal attack on the FB CEO's integrity without even understanding what an integrity team/dept does in these companies. I could just as well have been reading youtube comments. I see threads with some topics now and I can pretty much be sure to not expect to learn anything new or get a good discourse. Just people thinking they are better than others.
