@[email protected] I agree that #ActivityStreams2 is well designed. Maybe this is exactly because its ideas are actively tested in practice for several years in pump.io. Confusion of Actors and Users of servers in the #ActivityPub I regard as a conceptual mistake that should be fixed _now_. So I proposed concrete additions to the spec in this issue: https://github.com/w3c/activitypub/issues/260
