The We Want MoR podcast, a chapter by chapter read-through and discussion of Harry Potter and the Methods of Rationality by a Rationalist and a newbie, has just finished up Book One (Ch. 1-21) of HPMOR. (Apple Podcasts link.)
Less Wrong used to be a major locus of discussion for HPMOR, so I thought it made sense to share this here, especially now that the show has passed this milestone. If folks don't necessarily want to keep HPMOR content on Less Wrong, there are ongoing lively discussions of the weekly episodes on the r/hpmor subreddit.
Disclosure, I was the guest on this episode.
