Thanks for the link. The article explains some basic stuff, useful indeed but unrelated to the macro architecture used by the service.
Also, I noticed that the content is displayed contextually. If you access using incognito mode in browser the information is different compared to authenticated sessions.
I might be wrong, but the information is personalized based on (at least) two factors:

  • followed channels (this is a common technique)
  • cover item is updated if you already read that topic and refresh the page (I might be wrong on this)

This kind of "decision" should inject some decisional delay in the service speed. Well, still scores 100 on Lighthouse, witch is amazing IMO.
