Assume that nothing here is perfectly up to date or complete. While I may publish finished works here, the primary point of using this service for me is to be able to quickly and easily share things regardless of their stage of development. Things have been loosely organized into categories. As time goes on, some notes will end up in multiple categories.
Each category has its own page, but they are also all embedded in this page, so you can Ctrl+F or scroll to find things.
I've also started keeping a Shared Notes Changelog so you can see what has been most recently updated.
I am making the best effort I can to maintain archives of these pages on the Wayback Machine, Ghostarchive, and Archive.today, in case https://share.note.sx disappears. (Note: Due to inconsistency in availability and functionality, these archives will always be somewhat out of date.)

Due to an issue with Shared Notes, I have to keep a note with all MathJax glyphs used in other notes uploaded in its own place. That note is Shared Notes In-Use LaTeX Glyphs. Open if you wanna look at a lot of equations. ;P
