You are right about HN folks. I asked this question prompted by a topic discussed here during the past week, in which many people were commenting and sounding like experts. But because I knew deeply about it (having written my Master’s thesis on it), I noticed how mistaken they were — despite making their opinions sound like facts.
It makes me wonder: should this make us disregard many more discussions? Because what if the comments on those are as “untrustworthy” as the comments shown in that thread I know about?
