60 - Public Note Repositories - are collections of peoples personal notes made public. I’m still thinking about the utility of them. On one hand they are a good for showing others a tangible example of how to create a notes collections. My favorite so far is Andy’s Working Notes in terms of layout and quality of content.
It is not a particularly desirable way of communicating information to others because they aren’t structured for easy understanding. Instead what you’d want is either a blog (e.g. Wait But Why, Derek Sivers, and Farnam Street), site of curated articles (e.g. thoughtco or owlcation), or small wikis (e.g. SuperMemo Guru, AskHistorians Wiki). While these options are better than a standalone notes collection they are still lacking. Specifically they don’t do the best job of addressing the issue of match quality in learning.
The direction I am currently leaning is to make a Wiki with an explorable back end that is a zettelkasten. The homepage of the website would be a [table of contents] similar to my old github one which leads to wiki entries of similar size to supermemo guru. Inside each of the entries are links to the zettelkasten notes that were used to build them. You could also access the zettelkasten through an index, which would be a link in the sites navigation bar.
