I'm gonna be honest, I do use RSS, but I dread it due to a) not every website supporting it, b) random sites having feeds that are way too noisy, c) liking one category of posts or one author and failing to extract those posts only, or d) random people I like publishing on multiple websites.
Now I can get around it with a ton of effort, but it will break sooner or later, which is why why I find Twitter/Mastodon lists far more useful and flexible.
