I've put together a list of what I think are the best Yvain (Scott Alexander) posts for new readers, drawing from SlateStarCodex, LessWrong, and Scott's LiveJournal.

The list should make the most sense to people who start from the top and read through it in order, though skipping around is encouraged too. Rather than making a chronological list, I’ve tried to order things by a mix of "where do I think most people should start reading?" plus "sorting related posts together."

This is a work in progress; you’re invited to suggest things you’d add, remove, or shuffle around. Since many of the titles are a bit cryptic, I'm adding short descriptions. See my blog for a version without the descriptions.
