For the last few months, LessWrong has been working with Solenoid_Entity to record each curated post into audio form. Recordings to date can be found here and on all major Podcast apps when you search "LessWrong".
More recently, we added some UI so it's clear when audio is available on a post.

We are now scaling up the amount of audio recorded, and the question is, what should we prioritize?
We can records posts, Sequences, wiki-tags, etc...
Searching for this on Audible now and not finding it.
