It's unfortunate because of all the platforms it is one that gets the most human interaction in terms of real thoughtful humans willing to discuss things. I've tried a lot of platforms and dev.to is the best as writer from this perspective. Medium has better stats but that is about it.
It's super unfortunate that the best place to write is also the place most blocked. HN isn't the only one. Reddit also by default blocks dev.to. There are plenty of low quality articles on both sides.
I think the moral of the story is that there is too much garbage out there and a computer algorithm is incapable of making the distinction. HN is fine risking being behind the curve if it saves it readers from wading through it. That's a fine tradeoff but means it leaves things on the table.
