Facebook's Zuckerberg defends hacking

Facebook's billionaire CEO Mark Zuckerberg calls himself a hacker.

For most people, that word means something malicious - shady criminals who listen in on private voicemails, or anonymous villains who cripple websites and break into email accounts.

For Facebook, though, hacker means something different. It's an ideal that permeates the company's culture. It explains the push to try new ideas (even if they fail), and to promote new products quickly (even if they're imperfect). The hacker approach has made Facebook one of the world's most valuable internet companies. Hackers "believe that something can always be better, and that nothing is ever complete," Zuckerberg explains. "They just have to go fix it -often in the face of people who say it's impossible or are content with the status quo."
