Someday I was doing a live-coding stream on Twitch where I was coding some project and also taking notes by using markdown files and Vim as an editor. One of the few viewers chat me in Discord with the question "Do you take notes by Zettelkasten method?". As I mentioned, I didn't know about this method and related terms. And after this random message, I just googled the Zettelkasten method and I realized that this is that I tried to do it intuitively, subconsciously! I deep dive into the world of the Zettelkasten method, bidirectional links, services, and apps like Obsidian, Roam Research, etc.
