TIL that @Chris Aldrich described back in 2022 an index‑card notebook for note‑taking on the go: https://boffosocko.com/2022/12/01/index-card-accessories-for-note-taking-on-the-go/ . Fast‑forward to today and the concept is real: you can actually buy an index‑card notebook on Amazon for around $10. It's an incredible reminder that it's not unusual for completely unconnected people to converge on similar concepts when they're considering the same underlying problem. What’s even more interesting is how far the idea has evolved. I recently wrote about this in my Substack article: https://sevetech.substack.com/p/why-index-cards-are-still-the-most?utm_campaign=post-expanded-share&utm_medium=post%20viewer It’s a quick look at how index cards have grown from loose notes into structured systems for PKM, Zettelkasten, 2×2 frameworks, UML sketches, and even LLM‑ready prompts, all made more practical with the new Index Card Notebook format.
