This is closer to a shower thought, given I don’t really know much about how ActivityPub works. Has anyone, or is it even possible to, made an instance designed to work as say a FUSE file system?
I was mostly just thinking about how hard UIs are to make and thought “what if the content was the UI”.
Doesn’t this sound like Usenet?
The Fediverse and classical Usenet are so similar IMO. I think Usenet is just so old that nobody outside of pirates is familiar with it.
