What do you mean rss is a thing of the past? Youtube channels support it, youtube playlists support it, tumblr blogs support it, lesswrong supports it, webcomics I follow support it. Substack also supports it. Pretty sure wordpress and blogger support it. ok, realizing that I apparently don't follow many blogs that are still active.
