It stores the complete data for any given user post in its databases
That is not fully correct. The index the data from the different personal data servers, and they host the largest personal data server out there, but you can have your own PDS and interact with other Bluesky users without having to rely on their data.
This means each one has its own data model, internal storage architecture, and streams/APIs.
Yeah, but why? ActivityPub already provides the “data model” and the API. Internal storage is an implementation detail. Why do we continue to accept this idea that each different mode of interaction with the social graph requires an entirely separate server?
Because they were built for different purposes, they support different features
Like OP said, on bluesky is possible to have different “shells” that interact with the network. Why wouldn’t that be possible on ActivityPub?

It is not. A server that “speaks” the ActivityPub is not that difficult to build, I’ve done it. The complexity is in getting the data from the social graph into and creating a good UX for users who are too used with the “app-centric” mentality.

Not “stored on activitypub”, but each book could be represented with RDF (it could be something as sophisticated as using DublinCore or as simple as just using isbns to uniquely identity the books (
urn:isbn:1234556789) , and then each activity for “CombatWombatEsq read a book” would be an activity where you are the actor and the book is the object.
