#ActivityPub implementation really is bare-bones, but more right now is unnecessary. There are many unanswered questions, especially around privacy.
For example, what happens when a user changes their blog from Public to Private or Password-protected? The existence of an account in the fediverse gives away information we don't otherwise divulge on Write.as.
Also on the topic of #privacy, I'm building it so that readers get privacy by default, too.
Individual follows, boosts, and favorites are not shown to the author. In the future, if anything, authors will see a sum of each of these in their normal blog stats (e.g. "You have 46 followers in the fediverse")
Also because of this fact, federation will be opt-in.
Public blogs will automatically be discoverable via #webfinger and have their outboxes accessible. And since this is a paid feature and I want federation to be free, I'll add an option to let free users enable federation on their Unlisted blogs.
