Have been using RSS feeds almost 20 years now, since Google Reader and with Feedly since Reader was deprecated.
I don't think I've seen a single piece of news come across Reddit in any of the interests I follow that I haven't also seen via rss feeds +/- an hour of it's posting.
How do you know who to follow? For example, if I were interested in software architecture, I would need to follow 40 blogs, no? And how would I know if new ones pop up?
That's the hard part. It takes some time to curate a good list. One of the nice things about ttrss is that you can drop any url into the subscribe field and it'll search the page for RSS feeds. I'm sure other readers probably do something similar.
I stopped using RSS feeds when google reader went down. There aren't a lot of RSS feeds I'm interested in anymore. That being said, I hope RSS makes a comeback.
