Mark Zuckerberg was in his element today. The chief executive of Facebook got to unveil his company’s latest creation, Facebook Places, which adds location to the world’s largest social network. He got up on a makeshift stage in his company’s own cafeteria at its headquarters in Palo Alto, Calif. He mingled with the partners and members of Facebook’s own engineering team, high-fiving those who looked his age — only they didn’t have a net worth above $1 billion.

The affair started late and Zuckerberg had some awkward pauses while on stage. But the 26-year-old handled himself well enough as he introduced a new feature that will likely make rivals in the location-based services business tremble with fear. We’ve uploaded scenes from the press conference in several videos for your enjoyment. You’ll also see the company’s video describing Facebook Places, which lets you share your location with friends, find out where your friends are, and discover new places.

I always find it fascinating to see how one of the world’s youngest billionaires at one of the hottest companies in Silicon Valley handles himself on stage. He seems like a pretty ordinary guy, just one more coder among many. We have Zuckerberg’s presentation and a short section of the Q&A session as well.
