I started again to use RSS and Atom feeds last week.
I used to use facebook as an aggregator, but its curated list has become too poisoned since the pandemics and "political outbreaks" that followed. The algorithms noticed that I've been (automatically/inadvertently) interacting too much with such content, and decided to focus on that in order to keep me hooked.
Facebook and other platforms profit by subtracting value from society. I ask myself if that will stop someday.
If you want to go crazy with RSS and build your entire information stream on top of it, you might need some glue code that semi-automatically turns static markup to rss [0]. (Disclaimer: I am the author)
