I use RSS daily with Miniflux. Tiny Tiny RSS is another popular self hosted option and there are a number of freemium platforms like Feedly & Inoreader. I prefer to self host primarily for cost/no ads or tracking/private data. It's true that social media platforms don't support it but that's never been my personal use case - every news site or discussion group I like to keep up with has a feed and it's worked great for me.
