I like how every time this is brought up, Reddit is used as an example. But Reddit has far, far more interesting and nuanced discussions that includes many people at the top of their respective fields. Nobody noteworthy would do an AMA on HN, but they all do it on Reddit. A comment here or there doesn’t really move the needle on the over all trajectory.
HN is more of a midwit sort of place, where you don’t get the shitposters or the exceedingly brilliant because the band is so narrow and conformist that nobody wants to deal with being downvoted/removed over the most trivial things. And then when people find out just how wrong the audience here can be, as attested by actual professionals usually taking the top comment to correct the majority of, then you really just might as well not bother with HN at all and stick with Reddit for breadth and depth.
So yes, Reddit is probably the better place for this article, along with just about every other article posted here.
