Pity though. RSS / Atom was a fantastic concept and it’s a real pity big tech killed them off.
Basically, I get to see the latest post from a random feed. Nothing else. No lists of unread new posts from all the feeds. If I like the title and short summary, I click through to the website or blog itself where I can read the whole thing. There's no FOMO this way, or an information overload. Just one post a time.
Because the whole list of feeds is curated by myself, I know that everything is at least a little interesting. I even made a category with Youtube channels that I like, so I can skip their annoying recommended videos algo.
Next to this basic functionality, I made what I call 'Newspapers'. These are certain topics with a bunch of selected feeds attached, they get checked automatically in the background. When the Newspaper has enough articles, I see a new Newspaper appear. Otherwise it might take months before a feed is shown in the random selection.
One 'dream' of me is to have OPML be the discovery-glue between all kinds of individual personal websites and blogs. But this requires critical mass to have enough to discover and explore, and it needs some fun/interesting software way to do that.
Or you create a blog for yourself and you make a blogroll.
As for discovering new blogs, couple of options but there are more out there: https://ooh.directory, https://blogroll.org/
