I am looking for some #localFirst solution for blog authoring what would publish (all or some) posts to an activityPub server like to a relay, with publishing of new versions of posts as updates.
And fetch new posts, comments, mentions, messages, and reactions arrive to my local-first thing as a Feed or an Inbox.
Sounds like I want "Fido with formatting and attachments" over #ActivityPub .
The #Fido part is avoid need to be "always online", but sync that few times per day when have time for it
