I've got a 12,000+ note deck (over 80% of which I created myself), but for most of it I don't have any particular reason for thinking other Less Wrongers would be interested (Middle Ages, Japanese, Religion, etc...) and some of it is quite personal. Although, I am working on a liberal arts (Grammar, Logic, Rhetoric, Arithmetic, Geometry, Music Theory, and Astronomy) deck that is intended for consumption by people-other-than-me (specifically my son, when he is of appropriate age), but I'm not quite finished with it yet.
