Mark Zuckerberg speaks at BYU, calls Facebook "as much psychology and sociology as it is technology"

PROVO — There's more than a good chance you've heard of Mark Zuckerberg.

An adaptation of his story was featured in the recent Oscar-winning film "The Social Network," in 2010 he was named Time magazine's "Person of the Year" and the project he spawned in his little Harvard dorm room less than a decade ago, Facebook, has reached 500 million people worldwide — and nearly half of all Americans.

Taking the stage in his first public forum appearance wearing his trademark hoodie and jeans in a somewhat unusual pairing with Utah's senior U.S. Sen. Orrin Hatch, the two sat on faux-cozy adjacent armchairs as Zuckerberg fielded questions about the future of social media technology, entrepreneurship and education submitted through — you guessed it — BYU's Facebook page.

"I have to say I'm a little bit nervous — I've never spoken to a stadium of people before," he said to the crowd of almost 10,700 filling the Marriott Center on Friday.

As chairman of the U.S. Senate Republican High Tech Task Force, Hatch asked Zuckerberg to come to BYU after hearing him speak on the international implications of technology.

"The main reason I invited him is to finally have him accept me as a [Facebook] friend," Hatch joked as the forum began.

Reported to be worth $13.5 billion, Zuckerberg discussed the evolution of his social networking giant and how having a small team of passionate workers makes all the difference in serving half of a billion users.

"One thing that gets blown out of proportion is the emphasis on the individual," he said. "The success of Facebook is really all about the team that we've built. In any company that's going to be true. One of the things that we've focused on is keeping the company as small as possible … Facebook only has around 2,000 people. How do you do that? You make sure that every person you add to your company is really great."

Zuckerberg discussed the humble and unexpected beginnings of the company, starting out as a simple product he created as a college sophomore in 2004. He was quite certain, in fact, that if that company "was ever going to be built from what we were doing, then someone much more qualified than me would do it."

Within a few weeks, however, two-thirds of the Harvard student body was using the site and it "kind of just got out of control from there."
