// A feed is the initial entry point for all inbound Activitypub events.
// However, its primary and only user-facing use case is to be a collection
// of inbound messages, nothing else.
//
// Thus, the flow for inbound events is the following:
// If the event is a note:
//
// Add it to the receiving feed. If it's a reply and the feed is a default
// create a notification for the owner
//
// If it's an event:
//
// If the feed is not a default feed for a user, discard the event
// If it is the default feed for a user, create a notification for the owner
