I use NetNewsWire, an RSS reader on iOS and macOS. Ars Technica is the main tech news site I follow in there, but also follow a few dev blogs.
I find if I have too many general purpose tech news sites there is a lot of duplication of big stories, and the volume becomes overwhelming to the point I give up. So I try and keep it simple.
HN fills in some gaps, and I figure if a story is big/important enough, I’ll hear about it eventually.
