I def want to do this with Brainstorm once I address some backend database problems. Only show Follow Packs from users whose GrapeRank scores are above some threshold. And if multiple users create Follow Packs on the same topic, then combine them to create a composite Follow Pack curated by your Grapevine, similarly to the way that Brainstorm (still in alpha) currently uses GrapeRank scores to generate composite, Grapevine-curated NIP-56 reports:
