RSS never died. It got eulogised when Google Reader shut down in 2013 and the tech press moved on, but the feeds kept publishing. Every major news site, every podcast, most blogs — the XML is right there if you look.
What changed is that the default behaviour became to use the platform’s feed instead. The algorithm decides what you see on Twitter/X/Bluesky/Mastodon. The newsletter lands in an inbox shaped by another company’s priorities. RSS is the version where you made the list and the list updated chronologically.
NetNewsWire on Mac. Reeder on iOS. Both free or cheap. Both just work. The feed for this site is /index.xml if you want it.
