I love RSS, I used to have an OPML file of hundreds of feeds (mainly blogs/ppl I follow but also various company news feeds and other news content). Don’t know when it happened but for a few years I didn’t have a RSS reader because the sw just got too unmaintained and bad (on macOS / iOS).
But a few months back I finally took the time and set up a reader. Now I again get annoyed by sites that don’t offer feeds of their content. But RSS is still hands down the best eay to be notified and on top of vast amount of new content of various sites all over the Web.
