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)
