I was very interested in Zettelkasten, and bought "How to Take Smart Notes". I may be one of the few people who didn't like it: it was sorely in need of an editor and could have been 1/4th the size with the same amount of information, and I think it should've been called "
Why to Take Smart Notes". I wanted a how-to guide, but got a persuasion piece on why I should want to do the thing I was already interested enough in that I bought a book to learn how to do it.
Anyway, as interesting as it is, I don't see any way Zettelkasten is useful to me specifically. I get how it could be amazing for others, particularly authors, but I want knowledge retrieval more than knowledge synthesis. Basically, I need a personal wiki. I've found LYT, especially its Maps Of Content, to be an excellent resource for organizing the million and one things I want to drop into a PKM and be able to find later. For me, a web of information is much more useful than a serialization.
