I do love me some RSS. I started using RSS seriously 2 years ago, and last year, I forked Bubo RSS[1] to have my own RSS reader[2]. It's just a static site that is built every hour using Github Actions (although you can easily turn this into a cron job on your Raspberry Pi or whatever).

I liked the result so much, I ended up doing something similar using RSS feeds to a build page with all my of Youtube subscriptions[3].
