This is awesome. But, I hope Blake is fine with this. I did the same thing earlier, scraped the posts and created a epub. He immediately sent me an email:

Please remove the ePub version of my notes that you put on Github.

Peter Thiel, Clarium, and I are still figuring out what to do with the content. Very likely we will be publishing something ourselves.

As you do not own the content and did not ask for permission, please take down the doc immediately

(You can of course do this for personal use. Just please don't distribute it right now.)
