Depending on your deadline for the e-book... I'm in the process of reading the sequences right now (just finished mysterious answers to mysterious questions). If you want, I could agree to provide feedback as I go and also to finish them ASAP. I've already done work on improving my rationality like setting out to raze my cached thoughts (almost half my life ago, not triggered by the sequences), detecting biased reasoning in myself and learning about logical fallacies and I ran a writer's group for several years, so I'd probably give good feedback.

What is the deadline for the feedback / would you be interested in somebody reading it over with these and/or other concerns in mind?
