I use RSS every single day to collect the 500+ tech articles I scan every day. My blog is actually powered by its RSS feed to then push out to 8 other social networks. Don't know what I'd do without RSS.
I use self-hosted FreshRSS (after having tried a few other self-hosted ones - I did a video at https://youtu.be/nBdLgRSR04o which compares FreshRSS to Tiny Tiny RSS) and I paired it with Full-Text RSS Feed (see https://github.com/Dither/full-text-rss) to return the full content of posts.
