Even in the heyday of RSS how many of us just had an overgrown 10000+ unread RSS reader that we simply stopped using?
Promoting RSS seems backwards to me because that ship has sailed. Like promoting IRC when people have chosen solutions like Discord and then refusing to acknowledge why people prefer Discord. RSS (and IRC) didn’t just fall out of favor because people refuse to see how amazing it is nor is it just because of ads.
The answer to the post-RSS world is something more like a better, polished Fraidycat that can track content on any website. We can do better than RSS: a solution that doesn’t rely on everyone implementing it.
