This way of developing the #fediverse where each server only receive one kind of the objects accepted by #ActivityPub makes it more fragmented it, right? A server should send and receive all kinds of objects and should be up to the client to how to processes those objects.

If an user wants an Instagram-like app just create an account on any service and use and app with that UI, of lager they wanted to see more kinds of objects they should just use another client that supports Note, Article, etc. with the same account on the same server.

Ideally all server should have a shared API.

This fixes #fragmentation, the need to have multiple accounts if you are into multiple kinds of objects/content.

Imho, ActivityPub is a bad protocol that tries to accomplish everything, and ends up being bad at all of it. The spec is also ambiguous in a lot of areas. And major implementations don’t always follow the spec. All in all, it’s a miracle the fediverse even works as well as it does.

Instead of being "bad," I consider ActivityPub as not being mature yet.

Other internet protocol like HTTP or email are also really basic on its early inception, but it later adding so many features and capabilities to be more modern and flexible.

Give it enough time, and ActivityPub will be mature enough for varied use cases.

I didn’t say basic. I said bad. HTTP 1 is a good protocol. ActivityPub is not. Read both the specs if you don’t believe me. I have.

There’s not a single point in HTTP 1 that I thought, “what the fuck does that mean?” There are several in ActivityPub. ActivityPub also has several areas that are ambiguous. Ambiguity is bad in a specification.

ActivityPub tries to support everything, and has no defined behavior for when a client doesn’t support whatever thing it just received.

It also uses JSON-LD, which isn’t necessarily bad, but defeats the purpose of JSON by making it too complicated to easily write by hand.

This is not easy to write, read, or parse, or build:
