Richard, it's early, but at last weekend's IndieWeb Summit in Portland, a small group of us started tinkering on what we hope could be the Timeline of the Open Web.

At this point, it's wireframing and prototyping, but check it out! We call it "together" and you can find more information on it on the IndieWeb wiki - https://indieweb.org/together - and on GitHub - https://github.com/cleverdevil/together/

I believe that the what users will want isn't a traditional feed reader, but something more akin to the Facebook, Instagram, or Twitter timeline experience, but without nasty algorithms, ads, or surveillance capitalism.
