Oddbean new post about login | logout Does it? The client tag just helps people know what client published the note, which is a different thing from knowing how best to read the note, which is what handlers are for.
So you'd only look at kind 31989's published by users you know?
That's an extra action for the users to take (which very few currently do). @Zapstore might be the kind of app where it feels more natural for users to publicly recommend handlers.
Coracle looks for recommendations from people you follow, and surfaces any handlers that are recommended. This is all automatic, and shows up at the bottom of a note in a drop down you can use to open any recommended handler. It is an extra step, but I'm not sure how you could get it shorter.
