The key question here is: what the Zettelkasten really is?
There is argument about something which is not provided: definition of ZK.
When it will be the definition, then it can be argued, but so there are only two one-sided heads talking to themselves about different things, but which have something in common, so they can talk endlessly.
And it has nothing to do with knowledge management, note-taking or learning, because it can be done in many ways, so then there is no need to discuss about it in terms of misunderstanding.
Misunderstanding and fallacies can be talked in terms of definitions or ideas, but it should be any will to compromise some limitations and not putting everything under umbrella-terms.
Will someone discuss that bloggers write texts like ancient philosophers so for example Plato was very first blogger? There are texts and written thoughts in both cases, aren't they!?
