I just finished reading/listening to Accidental Billionaires: The Founding of Facebook A Tale of Sex, Money, Genius and Betrayal (Amazon). Wooooh! Catchy right? I think this is about the worst book I have ever read. And they are going to turn it into a movie, I hope not too closely based on the writing of the book.
Why did I hate it so much? For one it was the narrator of the audio version. His nasal, semi-cool, I-don't-give-a-crap kind of reading was kind of annoying. But the main reason was the fact that about every other paragraph starts with something like "we can imagine how Mark Zuckerberg..." Why? Because the author hasn't talked to Mark, the main character of this book. He hasn't talked to many of the people he writes about, so half of the story is dramatization of how the author imaged things to have gone.
"And there he sat behind his computer, the reflection of code in his eyes and monitor light on his pale skin. Behind the computer is where he felt at home, that's the only place he truly felt home."
If you're interested in Facebook's history, there's some information in this book that might be true, but it could be summarized in a few pages, and likely you can find all of it at wikipedia.
