I really enjoyed this article, thank you for sharing it. Sometimes it's easy to get lost in the intricate setups and in perfecting notes. It really is so individual and I think you are right about starting and refining the system as you go, to match your own needs. E.g. I enjoy a good tagging system, but I also really like keeping direct quotes (as they are, not in my own words; and reading a bit about zettelkasten would have be thinking that's an outrageous statement).
