Thanks for sharing this. I had not heard of Zettelkasten, but it is just like the site https://mathlore.org https://mathlore.org I created to help people collect math knowledge to study, learn, and explore mathematics. That is, just like in a Zettelkasten, mathlore.org is a collection of items where each one is a self contained piece of mathematical knowledge that links to other items. It is designed so that the more you add to the system, the more interconnected things are, and the more useful it is. I also decided to use tags instead of categories too. It is really cool to see the creator of Zettelkasten decided the same. Again thanks for sharing this because I tried to find others that had researched a similar approach for storing information that I was thinking of, but I couldn't find any. Now that I know about Zettelkasten I can gain a lot of knowledge in what works well and what doesn't in this approach. It is really cool to know that there are others that like this approach.
