I think of an explicit trust attestation as a statement that you trust someone in some context. And it seems to me that context should generally have an action and a category.

Examples:

- “Alice trusts Bob to curate nostr content (the action) in all categories.” A nostr follow could potentially be interpreted as equivalent to that statement.

- “Alice trusts Bob to recommend movies (the action) in the category of sci-fi (the category)”

- “Alice trusts Bob to edit her Wikifreedia articles (the action) in the category of economics (the category).”

- “Alice trusts Bob to edit ontologies (the action) in all WoT-related categories (the categories)”
