I write with a similar approach to zettelkasten. My technique is purely digital. Paper is too easy to lose, damage, or not have on you when you need it, compared to a digital file that can be copied, synced, and backed up. I keep everything in just one long file, which I think gives a similar feeling to what the article describes about notecards - by using folds and reordering where necessary it’s quite easy to always have whatever you want visible; there’s nothing forcibly hidden from you by a file structure. I use plain text (with a tiny bit of custom syntax highlighting) in vim, because I like the simplicity and it fits my needs. But I think a one-file approach could work fine in a Markdown or WYSIWYG format.
