Backed!
Oh, but I already read most of the sequences. Ah well, I can always secretly exchange my SO's ABBA CD with this (queue the "something's strange about the lyrics, and Agnetha sounds somewhat different, but I can't quite put my finger on it ...").
LessWrong is getting ready to release an actual book that covers most of the material found in the Sequences.
There have been a few posts about it in the past, here are two: the title debate, content optimization.
We've been asked if we'd like to produce the audiobook version and the answer is yes. This is a large undertaking. The finished product will probably be over 35 hours of audio.
To help mitigate our risk we've decided to Kickstarter the audiobook. This basically allows us to pre-sell it so we're not stuck with a large production cost and no revenue.
The kickstarter campaign is here: https://www.kickstarter.com/projects/1267969302/lesswrong-the-sequences-audiobook
If you haven't heard of us before we've already produced some sequences into audiobooks. You can see them and listen to samples which are indicative of the audio quality here.
