I have to dissent here: I actually stopped reading the sequences with several more to go because many of them have a very high words-to-content ratio (especially because they were written as separate blog posts over multiple days, and often take the time to summarize points from previous posts). I was really hoping that Eliezer's book would be a concise summary of the rationality content here, not only for my own benefit, but because let's face it: telling LW newcomers that they should probably get started reading the several hundred posts that make up the sequences is a pretty large barrier to entry.

Although, now that I think about it, I'm likely atypical. Even though I very much enjoyed (parts of) GEB, I thought it was very wordy and actually never finished it (quit around page 400).
