I'm not completely versed on the subject, but from my understanding RSS was actually intentionally killed off in a premeditated manner as it allowed users to choose how they interacted with the endless feed of streams that were emerging from some social media corners of the 'net. They wanted control, complete control, over what you would see and what you would have to scroll for hours to see and what you'd never see even if you scrolled forever. There was also some beef between Atom vs RSS I guess, which contributed to its downfall. But I remember using shit like Google Reader and having a level of control unimaginable to propriatery feeds like FaceBook and InstaGram.
So I say, bring it back! Lets have an RSS Renaissance, (I guess this is technically an XML doc, but it severs the same purpose). I've been wanting this to happen for years now, this is actually a fairly political issue and I hope everyone takes the correct side on it
Fun fact: almost all of the internet still has RSS feeds hidden somewhere. You don't need to deal with horrible dark pattern websites, just pop that bad boy into an RSS reader (or even thunderbird, go wild) and enjoy reading the articles with your own fonts, word wrap, etc. Cozy af.
