This morning, I saw that Chris Aldrich has written an excellent overview of zettlekasten-note taking techniques and history. Ton Zijlstra comments that the article is great, and is itself a product of a zettlekasten, so Chris is “practicing what he preaches”. I agree with Ton’s compliment, but I still have one nagging qualm – what does the zettlekasten itself look like? In July 2022, Chris Aldrich called for public examples of zettlekasten output, which he has created a great example in his recent post. But what about the zettlekasten itself? As I state in the title (a play on the classic Wendy’s hamburger commercial) – show us the beef! Show us what was collected and how it was collected so we (humanity) can try to learn from your experiences. Of all my looking through Zettlekasten.de, I have found only one post with semi-specific information about actual zettlekasten cards/notes. Sounds like a 30-day challenge is in order here…
