The real pro-tip here is that basically everything you read on HN for which you are not an expert has the appearance of expertise and authenticity. Once you see those same people speaking on a subject which you know a lot about, you realise that HN is only actually high-expertise on tech and entrepreneurship. The users here (myself included!) are probably quite good at programming, business, and maybe project management, which gives us false confidence in our abilities in every other field that exists.
