Thanks for an awesome post. I think that I have quite similar ideas to how you think about notes and note-taking, although the terminology is different. But even so, you raised several points that were not only linked to my own thinking, but gave me new thoughts and ideas to work with. Cheers for that.
I was just about to ask you what your system looked like Michael, but then I realized that you've tucked many of them into Hypothes.is at https://via.hypothes.is/https://www.zylstra.org/blog/2020/11/100-days-in-obsidian-pt-4-writing-notes/
