@silverpill @jenniferplusplus @julian i don't understand why anyone would need to go directly from a single post to a collection of activities having to do with the thread. isn't it enough to pass through the thread itself first? e.g. take the Note.context.outbox for an "activity log", or if you're going to define a new property, then define it on the thread instead of on the post -- Note.context.history for example following https://w3id.org/fep/bad1
