RSS (in the sense of using a reader to track a personally curated set of RSS feeds) is pretty niche these days. One audience is journalists who really do want to discover news from a variety of sources faster than someone else does.

Most people are fine though with just using social. If it's noteworthy enough they figure they'll learn about it soon enough. Personally, I do have Feedly configured but I confess I don't use it systematically any longer.

I'm still a bit puzzled about Google shooting Reader. Keeping it would have been a tiny effort and it doesn't seem much removed from a mission of selling ads (excuse me, organizing information). But, then, Google has largely walked back/de-emphasized pretty much all their information curation projects other than straight search.
