I’m guessing this has not been much of a problem yet, but we can anticipate that it likely will become a problem at some point.

I’m thinking about how best to apply centrality scores like nostr:npub1xdtducdnjerex88gkg2qk2atsdlqsyxqaag4h05jmcpyspqt30wscmntxy ‘s TrustRank or my GrapeRank to sort content. These scores can be personalized, but they take a lot of work and computation and might be too burdensome to expect every client to implement independently. So scores could be calculated elsewhere and then exposed via API to clients like Primal who employ them in content curation.
