#GhostBlog is beginning #ActivityPub development for Ghost, while also still figuring out exactly which features they want to implement.
They have a form here for feedback, particularly for Ghost blog managers:

#GhostBlog has started implementing #ActivityPub endpoints for /actor/:id, /key/:id, /inbox/:id, /outbox/:id and /.well-known/webfinger
From commit:
"WebFinger is the protocol which allows different ActivityPub implementers to find information about Actors, it's could be thought of as the entrypoint. Given a username like @user@site.com, we can look up the URL for the Actor at
https://website.com/.well-known/webfinger?resource=acct:user@site.com
This would then give us info needed to discover the Actors Inbox & Outbox"
