I became aware of Zettlekasten last year sometime, but it seems like I have been using it for years. Many years ago I started using nvALT, the backend of which is now used for several Zettlekasten apps. nvALT allows linking between notes, so I always referred to it as my "text file database". I have used nvALT over the years to keep track of all my haiku research, all the thousands of haiku I have translated, my Japanese history research, and... well, and so on. When I learned of Zettlekasten last year I was shocked to discovered that it was basically what I had been doing for years, though his method was much more meticulous than mine. Very interesting!

OH you are definitely using the Zettlekasten method. I'm currently reading "How to Take Smart Notes" by Sonke Ahrens. He talks about Luhmann's system and then points out that it's not so much following his system as the concept behind it, which is keeping it simple enough to grow and be useful without having to keep restructuring it.
You must be killin' it out here!

You earned 1.000 PIMP for the strong hand.
You can still slap 1/2 more people today.
