For some reason, I could never get into RSS readers. I tried, but quickly felt overwhelmed and gave up. I've tried to get back into it over and over again, but always get just absolutely rocked by the amount of content that can be pulled in and get discouraged. It's also hard and daunting to think about getting into it at this point, now, because there's so much content out there that I don't even know where to start with adding RSS links of stuff I follow...because sometimes I don't even know where I get my stuff from (just from all over, Instagram, Twitter, Reddit, email newsletters, kbin, Google News, etc.)
A big part of it, I think, is the fact that RSS doesn’t have community curated content. to me, it just seems like such a wave of news content...but a lot of what I enjoyed about Reddit/social media (including kbin) is the community aspect, allowing for more nuanced and popular stuff to be driven to the top of the feed (based on upvotes, retweets, user activity, clicks, or what have you). So the lack of that in RSS stuff really hinders me from fully adopting it.
The trick to enjoy curated content via RSS is to subscribe to sources that curate your content rather than to raw news sources, e.g. subscribe a blog of a person that does important news reviews rather than to a newspaper raw feed. Otherwise the classic mailbox-like RSS reader experience indeed requires you to sift through content on your own and aggressively. That said, some commercial readers do try to algorithmically prioritize content based on your interest or offer discovery functions (a different kind of experience than direct community-based sorting of course, but there's trade offs here)
