Each instance has only one AP Actor that publishes each event. We are considering the introduction of other “Actor” but they will not be linked to users, rather to places or tags/categories. There are no personal homes with a timeline of people I follow, everyone has a sort of local timeline of the instance, it’s an anti filter-bubble feature.
Events are not published with the type
Event but with type
Note because we wanted to add the possibility to interact with events from mastodon instances (boost / bookmark and “comments” that we call resources because we don’t want it to become a place of debate, but more a place where to keep a historical memory of events, e.g. an audio recording of a talk).
When mastodon will support
Event object type we will change for sure.
