>The subscription process is simplicity itself
You must've found some different sites than I have, because even sites that have a feed don't make it obvious how. For instance, check out Substack, ex: https://steady.substack.com/p/america-the-beautiful
Can I get an RSS feed, and if so how? The giant "Subscribe" button isn't it. So I guess grab the page URL and paste it into Feedly and see what I get. I don't mind this (much), but "mass market" it ain't. And this kind of process is very common in my experience. Back in the day sites would have the little "feed" icon sometimes and that helped, but it was still a 2-3 step process.
