Old.iris.to has the slider - show me only one hop, two hops, three hops away etc..

Some apps, I think coracle is one of them, somehow calculate a WOT score of sorts.

Damus has notification friends toggle, and a show shared follows in profile view.

nostr:npub10r8xl2njyepcw2zwv3a6dyufj4e4ajx86hz6v4ehu4gnpupxxp7stjt2p8 adds WOT to the appstore - which of my friends follow, or verify an apps sha256 hash..
