The "old web" never really went a way. The "new web" just got better and more engaging. I still use my rss reader as my primary way to connect to the internet, but rss has problems and the readers did not evolve to solve them. The main problems are it is easy to drown in articles and hard to discover new feeds. Social media sites solve booth of these problems with their algorithms, but rss never found a solution for that. Thats why I started my own reader https://ivyreader.com to reduce the issues rss has, because I really hope it stays.
