Any book that begins with the CEO of a billion dollar company throwing up into a bin has my attention. The story was so compelling I found it hard to put down. It's a great insight into startups and the people who build them.
Having said that, Bilton could have talked more about the technology behind twitter, be less judgemental, and not colourify mundane scenes like ordering food at restaurants.
All in all, a great book deserving of high praise.
