I care about follower counts actually. But not in this intransparent way it's implemented in some clients right now. I want to see the back-follower count of first, second and third degree.
On nostr it's relatively quick to find all my follows, their follows and their follows. That's what I would consider most relevant accounts. If they all follow me, awesome! If a million others follow me? I couldn't care less.
I want a client that surfaces first what my follows authored and then what they re-posted/liked/zapped/commented but when things get crowded, I wouldn't want to see reactions or replies from people outside of this circle.
