Agreed. People think it is important to them. It may even impart information they can use to better themselves, not that it necessarily must. It’s entertainment primarily by virtue of usage if not of intent, as in the case of HN.
It's really unfair to clump all of entertainment together. Is watching reality TV same as discussing tech medium? Even if you boil "entertainment" down to "gives you fun points" one clearly gives you something more than that.
I think reading HN and watching reality TV are a lot closer than you think. The obvious difference is that you apparently have contempt for one and not the other. But I challenge the idea that you're being enriched any more by posting on HN.
Maybe you learn some new things here and there the same way someone who watches a lot of Elimidate might pick up some social skills/awareness.
But notice how convenient it is to attribute bad qualities to the thing you don't even enjoy in the first place, and positive qualities to the thing you do enjoy.
It's completely absurd to think that watching reality tv would give you any social or marketing skills — if anything I'd argue it's the complete opposite.

Honestly, in a lot of cases, yeah. I'm never going to use the vast majority of what I read about on HN, it's simply not in my sphere of work - it's fairly pure entertainment.
