I am skeptical, especially in the context of nostr. Nostr, as currently implemented, can't even accurately count followers. I do not see how a proper WoT can be built with that basic parameter being so wonky all the time. Build your own WoT, just like you would IRL. Don't rely on others. That's what I've done. I love my feed. It's weird enough to keep me coming back without repulsing me and it's cozy enough so I smile and learn things. I doubt a systematized approach will be able to do that.
