I follow dozens of subs through RSS and that’s pretty good. You just need a reader which has features to filter out certain users and words (like Newsblur what I use)

Yep, if you haven't lost the will to put a bit of curation work upfront, RSS never stopped being the right answer. Substack has been a pretty good addition to the landscape, bringing lots of people into blogging (without calling it that). But for the skimming/reading interface, RSS beats the app.
