I noticed. Endorsing content you like and people you trust is a powerful tool. Your followers doing this (interacting with your main profile) is the reason your content reaches me, and why we have all sorts of interactions despite not following each other directly.
They stop following you, your content stops reaching my feed (and vice-versa unless you are using one of the indirect ways to keep up with me mentioned above).
There has to be a way to solve Nostr’s cultural issue of “degrees of separation and endorsement from Jack / Odell / Derek / Lyn / Will, etc.” as a measure visibity without burning down the social graph and scorching the earth behind us.
My hypothesis is that we need a culture of more intentional following like what you're advocating for, but with proper ownertrust-style tools. I've asked around and a lot of people want to “follow that one person who produces crappy content we’re all embarrassed by, but we still love them regardless”. So kind 3 is better than nothing but not sufficient for WoT.
My main problem is how to bake in that intentionality in a way that’s accessible and fun instead of recreating a dumbed-down version of the PGP Web of Trust experience. It’s definitely an interesting research problem, one I don't have an immediate answer for, unfortunately.
