Nice thread! I am in the act of switching over to RSS.
I use RSS Mobile on iOS. It is an old app basic and no adds. Then the Vivaldi browser's built in RSS reader.
I'm in sound-art-noise orbits and have venue RSS feeds on my reader - seems if it is a CMS blog there is RSS. This is great cuz so many venues and booking agents are on meta & I deleted my meta account.
Last bit, I made my own RSS using XML - so crazy dang EASY to do
