Hatching Twitter is a great read, telling the story of how Twitter rose, somewhat haphazardly from Blogger and then Odeo. The story focuses on the backgrounds, personalities and infighting between the four co-founders (Noah Glass, Jack Dorsey, Biz Stone, Evan Williams) and it's a fascinating read. You're left wondering how the company was ever successful given the dysfunction throughout its history. I thoroughly enjoyed the book but I would have two complaints. Firstly, this book takes the Evan Williams side throughout and he was clearly one of the more active participants (though all four co-founders were interviewed). Jack Dorsey in particular gets a very rough treatment being characterised as incompetent, narrow-minded, scheming and Machiavellian at various points. Maybe this is correct, but I couldn't help feel that the book lacked balance. Secondly, the book focuses almost solely on the people, not the product. It would have been fascinating to see how the product developed, how features were decided and added, and how the service we know today took shape. But this is sadly glossed over at best.
In summary, a great read, had me gripped, but has left me wanting to get another perspective and learn more about the company.
