is https://ghost.org on #ActivityPub yet? 😅

Seriously I've been hearing about #Ghost supporting ActivityPub for awhile now.

Or, even though ActivityPub does not in general require WebFinger, is Ghost on WebFinger?

Please reply with a URL hosted by Ghost that is retrievable using ActivityPub and/or resolvable in Mastodon. 🙏

AFAICT none of the URLs on Ghost are retrievable as ActivityPub Objects.
