Glose, a recent ebook startup, allows its readers to read for free the entire book.
Since I also build an ebook reading app (Addr, check it on the App Store if you will), I wondered whether or not we could implement a copy of Hackers and Painters as a free sort of 'tutorial' book.
Alright. After further research, I realized Glose actually does not "sell" the Hackers and Painters book. They "only" give to read a bunch of blog posts pg has written for three or four years. My mistake.
