I Use Hacker News for technical input.
on an average, HN crowd is pretty clueless about
a) running a profitable business
b) foreseeing technological progress -- say two iterations down the line.
c) mass adoption of features
On an average, they tend to be elitist and don't represent the average brand popularity (e.g Google, Meta, Amazon). They only mildly upvote technology that helps their extremely privileged life.
E.g Current AI / Metaverse features helps plenty of poor, underprivileged people around the world, especially non-english speaking. But HN is the first to mock such features.
Because of this, they tend to be poor individual stock pickers. They are highly risk-averse and typically bring an SRE mentality to the world.
