I can't mail that address, I get a failure message from Google:

I'll post my feedback here:

Hello,

I got the book "Rationality: From AI to Zombies" via intelligence.org/e-junkie for my Kindle (5th gen, not the paperwhite/touch/fire). So far I've read a dozen pages, but since it will take me a while to get to the end of the book I'll give some feedback right away:

• The book looks great! Some other ebooks I have don't use page-breaks at the end of a chapter, don't have a Table of Content, have inconsistent font types/sizes etc. The PDF version is very pretty as well.

• The filename "Rationality.mobi" (AI-Zombie) is the same as "rationality.mobi" (HPMOR)

• A bunch of inter-book links such as "The Twelve Virtues of Rationality"/"Predictably Wrong"/"Fake Beliefs"/"Noticing Confusion" (all from Biases: An introduction) don't work: On my Kindle I have the option to "Follow link", but when I choose it the page refreshes and I'm still at the same spot.

  Inspecting the .mobi source with Calibre e-book reader I see:

  < a href="XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX" >Noticing Confusion< /a>

  The links from the TOCs and some other chapters do work properly.

• Due to the lack of quotation marks and the nonuse of italics I didn't realize the part "As a consequence, it might be necessary" was a quote (Biases: An introduction). The extra margin left and right do indicate something special, but with the experience of so many bad ebooks my brain assumed it was just a broken indentation level.

• The difference between a link going to the web and one going to a location within the book aren't obvious: one is only a slighter darker grey than the other. In Calibri the links are a nice green/blue, but my kindle doesn't have colours.

Cheers,
