While looking at a #zettelkasten on Ancient Egyptian, I just ran across an actively maintained scholarly zettelkasten with over 10 million individual slips!!! One of the largest sub-sectional topics alone has over 90,000 slips. Eat your heart out Niklas Luhmann!
Does this cast you as Dr. W. C. Minor in the story, albeit not in the same sort of mad man way to wordnik’s Sir James Murray? Seriously though, this is an awesome use case.
