1. Sovereign WoT enables you and your community to identify who is the most trustworthy, and in what context, to curate content, facts, and information. 
2. Proxy indicators of trust have their uses but they are a crutch that we must wean ourselves off of. Explicit trust attestations are essential.
3. Explicit trust must be contextual. A nostr follows list can be loosely translated / interpreted as “Alice trusts Bob to curate (or maybe merely to create) nostr content for her nostr feed.” Context should have an action and a category. Examples: “Alice trusts Bob to recommend movies (the action) in the category of sci-fi (the category)” or “Alice trusts Bob to edit her Wikifreedia articles (the action) in the category of economics (the category).” Or “Alice trusts Bob to edit ontologies (the action) in all WoT-related categories (the categories)”
4. Sovereign WoT must be portable. Not limited by nostr clients. Not even limited by nostr.
5. ANY and ALL of these and more. Sovereign WoT must be portable beyond nostr.
