Vincent Ritter, introducing Sublime Feed makes a point that feels like it was just for me:

There is also no concept of “unread”. I don’t need that in my life… and I know some of you do. I think having an unread count isn’t healthy. Each time you load up your feed it’s a snapshot of this very moment in time and you can just pick and choose. I think it’s easy enough to remember the post you just read and move onto the other.

I agree with this, mostly. Given that I’ve given up on remembering every little thing, Sublime Feed will be a place in which I will only read my favourites.
