Time Person of the Year 2010: Facebook's Mark Zuckerberg

Zuckerberg has often — possibly always — been described as remote and socially awkward, but that’s not quite right. True: holding a conversation with him can be challenging. He approaches conversation as a way of exchanging data as rapidly and efficiently as possible, rather than as a recreational activity undertaken for its own sake. He is formidably quick and talks rapidly and precisely, and if he has no data to transmit, he abruptly falls silent. (“I usually don’t like things that are too much about me” was how he began our first interview.) He cannot be relied on to throw the ball back or give you encouraging facial cues. His default expression is a direct and slightly wide-eyed stare that makes you wonder if you’ve got a spider on your forehead.
