So true! This has bugged me enough to create a introduction to Zettelkasten myself - just one page - https://binnyva.com/zettelkasten/ (wanted to keep it under 500 - but it went to 700 words).

Too many my friends are getting the idea Zettelkasten is complicated. When anyone express interest, I make it a point to tell them its a very simple concept. The complication is more in creating the behavior of taking notes rather than in using the system.
