One of the toughest parts about these systems is that while they're relatively easy to outline (evidence: the thousands of 500-1000 word blog posts about zettelkasten in the last 3 years), they're tougher to practice and many people have slight variations on the idea (from Eminem's "Stacking Ammo" to Luhmann's (still incomplete) digital collection). Far fewer people are sticking with it beyond a few weeks or doing it for crazy reasons (I call it #ProductivityPorn, while Scott has the colorful phrase "bubble graph boys").
For those who visit here, seeing discrete cards and ideas, videos, or examples of how others have done this practice can be immensely helpful. While it can be boring to watch a video of someone reading and taking notes by hand, it can also be incredibly useful to see exactly what they're doing and how they're doing it (though God bless you for speeding them up 😅).
This is also part of why I share examples of how others have practiced these techniques too. Seeing discrete examples to imitate is far easier than trying to innovate your way into these methods, particularly when it's difficult to see the acceleration effects of serendipity that comes several months or years into the process. Plus it's fun to see how Vladimir Nabokov, Anne Lamott, Gottfried Wilhelm Leibniz, Bob Hope, Michael Ende, Twyla Tharp, Roland Barthes, Kate Grenville, Marcel Mauss, Claude Lévi-Strauss, Joan Rivers, Umberto Eco, Georg Christoph Lichtenberg, Raymond, Llull, George Carlin, John Locke, and Eminem all did variations of this for themselves. (This last sentence has so much entropy in it, I'm certain that it's never been written before in the history of humanity.)
And isn't everyone tired to death of Luhmann, Luhmann, Luhmann? You'd think that no one had ever thought to take note of anything before?!
While my own approach is a hybrid of online and offline techniques, I've gotten long emails from people following my Hypothes.is feed of notes and annotations saying what a useful extended example it is. Of course they don't see the follow up that entails revision of the notes or additional linking, tagging, and indexing that may go on, but it's at least enough of an idea that they understand the start of the practice.
(Incidentally, I wrote most of this using a few cards from my own system. 🗃️✂️🖋️)
