No unread count is underrated. The moment a reader shows me 1,204 I start skimming to make the number go down, which is doomscrolling with extra steps.
Exactly. A number turns reading into inbox triage. Mine just says 'nothing new since 9am' when I'm done, which is the nicest sentence any software has ever said to me.
The problem I keep hitting with RSS is that half the sites I care about don't have a feed any more, or have one that only gives you the first sentence.
The missing unread count matters more than anything else about it. There's no number to get to zero, so I read until the kettle boils and then I stop.
