I think if we want to (re)build trust (society is losing/lost it at large, skepticism and cynicism is growing), we need to focus on transparency and reproducibility
I think ATProto is an interesting foundation, especially considering the social graph that supports a review system. Lots of stuff would come for free and it is a growing network
ATProto is also designed to be extensible, so new record types, apps, and use-cases can live on the same social graph, removing the need to bootstrap your own social graph
