I've not seen this explicitly laid out as advice before though in most contexts people's note taking spaces have historically been divorced from their writing spaces for publication because slips and notes are usually kept physically separate from the working spaces or finished parts, but Richard Carter specifically separates the digital spaces in which he takes his notes and then uses them for creating end products. While he could both take notes in Obsidian, his tool of choice for notes, as well as write his finished pieces there, he actively changes contexts to use a different digital app to compose his notes into final pieces.

What affordances does this context shift provide? <br /> - blank slate may encourage reworking and expansion of original notes - is there a blank slate effect and what would it entail? - potentially moves the piece into a longer format space or tool which provides additional writing, formatting or other affordances (which? there don't seem to be any in this case aside from a potential "distraction free mode" which may tend to force one to focus only on the piece at hand rather than the thousands of other pieces (notes) hiding within the app)

What affordances does this remove?<br /> - He's forced to repeat himself (cut & paste / DRY violation)

Is it easier or harder (from a time/effort perspective) to provide citations with such a workflow? Carter does indicate that for him:

Having links to original sources in my outline makes the compilation of references for the chapter far easier than it used to be.

The important part of permanent notes are generating your own ideas and connecting (linking them densely) into your note system. The linking part is important and can be the part that most using digital systems forget to do. In paper zettelkasten, one was forced to create the first link by placing the note into the system for the first time. This can specifically be seen in Niklas Luhmann's example where a note became a new area of its own or, far more likely, it was linked to prior ideas.

By linking the idea to others within the system, it becomes more likely that the idea can have additional multiple contexts where it might be used and improve the fact that context shifts will prove more insight in the future.

Additional links to subject headings, tags, categories, or other forms of taxonomy will also help to make sure the note isn't lost completely into the system. Links to the bibliographical references within the system are helpful as well, especially for later citation. Keep in mind that these categories and reference links aren't nearly as valuable as the other primary idea links.

One can surely collect ideas and facts into their system, but these aren't as important or as interesting as one's own ideas and the things that are sparked and generated by them.

Asking questions in permanent notes can be valuable as they can become the context for new research, projects, and writing. Open questions can be incredibly valuable for one's thinking and explorations.

It may be worth it programming a bot that brings this information to wikidata
