Back in the site's early days, Facebook co-founder and CEO Mark Zuckerberg "acted like he was captain of a pirate ship," handed out business cards that read, "I'm CEO...B**ch," and rarely got up before noon.
These are just a few of the revelations from David Kirkpatrick's new book on Facebook, The Facebook Effect: the Inside Story of the Company That Is Connecting the World.

'Zuckerberg slept later than most -- he seldom got to work in the equipment-jammed dining room before afternoon. His typical garb in the office was pajama bottoms and a T-shirt. When the software code-writing got intense, he was a taskmaster. If someone got hungry and wanted to go out for fast food, recalls a frequent visitor, "Mark would, like, pound the table and just say, 'No! We're in lockdown! No one leaves the table until we're done with this thing." Zuckerberg was determined to keep this ship moving forward, and he was more than happy to be the captain.
Not infrequently, he acted like he was captain of a pirate ship. Among the few possessions he had brought to Silicon Valley with him were his fencing paraphernalia, which he left lying in a pile. Often he'd grab his foil and start swinging it through the air. "Okay, we've got to talk about this," he would declare, one hand held behind his back, lunging forward with this foil. Often the sword would get uncomfortably close to people's faces.'
