What's the difference between my journal and my stream?
I'll first describe what is the current state of affairs. This does not necessarily align with the way I desire things to be.
Current state of affairs
I write my journal in org-roam. It is a bulleted list of thoughts. It is read-only - noone can interact with it directly. (Though of course, people could annotate it with hypothesis, or something similar). It is not structured - you could not subscribe to items within it in a feed reader, say. It is public, and is thus filtered - despite the name, I don't put much personal or intimate things in this public journal.
I publish to my stream via micropub and WordPress, and syndicate it to Mastodon. My stream allows for comments and interactions.
What goes in my stream is generally a subset of my journal. But responses to comments in my stream are not necessarily included in my journal. (Though likely pulled in to my garden in the relevant place.)
A desire for how things should be
Not sure. It's fine at the moment. Just a vague feeling that perhaps they should be combined. But this might be mistaken.
