This looks like an interesting public Zettelkasten
In doing some research for an article, I stumbled on this, which appears to be (as far as I can say: it is in German, and my German is not great) a public-facing Zettelkasten about a history of dissent and revolution. I know nothing about the author, but I thought it was an interesting example of using a Zettel as a public teaching tool, as well a glimpse into how someone else approaches conceptual linking.
If anyone who actually reads German wants to give more detail or correct my assumptions, I would be thankful.
