I can't read any of that because I'm distracted by the mental image of Bill telling someone the best books he read, with some conversation, and that person asking some questions while writing notes, then spending hours in front of his laptop, emailing a draft to someone else, who asks Bill a few more questions then returns a draft to someone else who finalizes it and publishes on "GatesNotes" written as if he sat down on his blogging backend and typed it out in a textfield.
I have no idea the process behind this website, but it seems unlikely enough that he'd sit down and write it himself that I can't take it seriously. From what little I read, it doesn't sound like something produced directly from him without first passing through others, at least for formatting and correction.
