Fediverse

I skimmed the first few pages. And it seems it's just concerned with the content? You can store your notes (posts, file uploads, ...) on arbitrary instances and move them around. But you still need a fixed instance that hosts your actor identity (your account) which then tells where to go to fetch a post. And that one can't change. So your account and username would still be tied to a fixed domain handle. And you can't move it. And even for the content, it seems like you'd need that fixed instance to do the 302 forward, so it needs to be contacted to resolve each location.

Edit: But you might be right. I don't grasp the full concept. Maybe it enables us to configure a webserver on our own domain to forward a user handle to some external server. Meaning we don't have to install a server ourselves. And the servers would then be interchangable (if this translates to fetching everything). You'd still be tied to your domain name. But not to a service anymore. That'd be great.
