I think RSS is pretty neat. And Mastodon makes it really simple to become a publishing technology power user, even without fiddling with feeds yourself.
You can use it to curate your own information needs via searches right from within Mastodon (well, you could upgrade to full information junkie and get a dedicated feed reader) and you can use it to selectively push your information elsewhere in a computer readable format.
