All I see is people claiming RSS is dead, but I never stopped. Moving between various readers and landed on Feedly for iOS a few years ago. Love it.
It's not dead, but many things I wish supported RSS don't. Facebook. Twitter. Instagram. These would be incredibly useful things to have native RSS feeds for, but instead I have to dig around and either use some tool someone built for the purpose - a tool at the mercy of the walled garden whose wall they're peeking over - or build my own nightmare factory.
If Facebook had any kind of API I could probably build this, and stop using facebook otherwise. Which is probably why they don't?
