I'm currently going through the pain of ActivityPubbing my blog. The single thought that is screaming out at me right now is, 'If we want to encourage a web of independent micro-servers, we must do more to help each other get the protocols right.'
I really think there ought to be the means in AP to send diagnostic information back to a sender if a receiver can't work with a given message, like, 'You didn't give me an inbox.'
Am I alone in these thoughts?
