@robertbreen Thanks for this reply - you're describing an interesting process. What kind of tags do you use? Are they subject-based (e.g. 'biology') or process-based (e.g. 'blog-post idea'), or both?
Funnily enough this doesn't seem very far removed from my own practice of note-making. I sometimes write a long, meandering journal entry, then return to it later to extract more 'atomic' notes from it by means of transclusion.
In a way this reflects a much older practice, from the era when paper was scarce and expensive. People would make rough notes on reusable wax or slate tablets, then transcribe what they really wanted to preserve later, onto paper. This two-step process allows for reflection and refinement, even if it does require a bit more work.
