I just discovered this while researching note-taking methodologies. It seems quite new; the only mentions of it on social media are “look at this new thing.”<p>It's not a product or service (yet?); it's just a collection of instructions and some resources for setting up Apple Notes in a structured way to keep your notes organized.<p>I don't use Apple Notes, but the concept is simple enough that it can be used with any notes app. I adopted it to use with iA Writer, and there are others in the Obsidian Discord server talking about taking it on.<p>The ideas aren't new (it uses aspects of Zettelkasten, Evergreen Notes, GTD, Bullet Journal, et al), but the presentation is nice, and completely free.
