I find the idea of a #zettelkasten really cozy. Before computers, some people kept notebooks with their notes and thoughts. I see my digital ZK as a version of that, ignoring any claims about productivity or second brain, which I feel are a bit cargo-culty. I've had my ZK for six years know (lots of free time during Covid). It's a directory containing plain text (markdown) files that link to each other. It's that simple. An app can take this and make a bit more out of it. For example, being able to have both a graph and tree view of my notes is great. Gives back a bit of that spatial dimension that is lost when going digital. I got close to the concept of a ZK through #Obsidian. But I also use mine through a terminal text editor. That's the beauty of #LocalFirst and #PlainText. I also mirror it on my phone so I can carry it around. It's like having your own #Web, but without @timbl's genius idea of using links to navigate the Internet. You can still have external links though.
