I also had this come across my feed. Always funny to see articles about the death of RSS in my RSS reader. Honestly, the idea of using the web _without_ RSS is entirely alien to me at this point; I don't understand how people keep track of what they've read, what they're going to read, what they liked, etc. without a feed.
I used RSS a bit a few years back. Other than getting a stream of text without ads which was good, I now use reader view for that and bookmarking sites I want to revisit with raindrop. I didn't really see the need for it.. Is there a RSS linux client that has tracking features described above? I want to try it out.
