In reply to Bastian.

RSS isn’t really a format that has to change. It’s just a stream of data.

Think of it like all of Twitter’s content, but with no Twitter app or site to interpret it, so that’s where RSS clients come into play.

Just like how you need a Twitter app to fully experience Twitter, you plug those RSS feeds into a good RSS client, like NetNewsWire https://netnewswire.com/ (also free and open source), and suddenly you have the “notifications, ease of use, etc.” that you were looking for.
