So like a single ActivityPub instance that hosts all the data, but users can have a Pixelfed app, Lemmy app, etc. all connect to that one server and use it to give the experience they specifically provide.

That's a cool idea. I can see how that would work.

And that's great! Everyone gets what they want. But suggesting Lemmy, Pixelfed, and Peertube, etc. should all try to do it the way Friendica does, is a bad idea.

If I have a mutual who is on multiple platforms, and I also have accounts on those same multiple platforms, we would generally be following each other mutually on those same platforms.

But your saying Peertube should have all the forum functionality of Lemmy, and the endless short video scroll of Loops.

rgluilis suggested a generic server idea, where the media and experience differentiating is done at the client app level. That could work well. But that's an entirely different cincpet and structure.

The writing in this article it absolutely terrible. It needs some serious clean-up before the message isn't impaired by the medium.

You jest, but I'm pretty sure someone out there made a cli interface for AP.
