What We Learned About Mark Zuckerberg From His Candid Talk With Users

He's not cool and not into appletinis

Mark Zuckerberg finally admitted it: He's not cool, and he never built Facebook to be cool or meet girls. Oh, and he never heard of an apple martini before the movie The Social Network.

The Facebook CEO held a public forum, streamed online today, to answer questions ranging from why the social network controls the News Feed to why he wears the same shirt everyday.

The "cool" question came up, as it has for the past year, with people wondering if Facebook is still cool or are teens not using the service as much?

"My goal was never really to make Facebook cool. I am not a cool person, and I've never really tried to be cool," Zuckerberg told the audience at his company's Menlo Park, Calif., headquarters. He said Facebook doesn’t need to be cool, it just needs to work, like light bulbs. "No one says, 'Yeah, electricity,'" he said.

That's actually part of the reason why he had problems with the movie The Social Network, which he said his company had fun with but didn't take seriously.

"They kind of made up a bunch of stuff that I found hurtful," Zuckerberg said. He said the No. 1 mischaracterization was that he built Facebook to get girls. He was dating his wife-to-be when Facebook launched.

After the movie, which he took the whole company to see at the time, appletinis became an inside joke. He said he never heard of the drink that he appeared to love in the movie about his life.

Now, about why he wears the same T-shirt everyday—it's a thing geniuses do, he said. Steve Jobs wore the same thing, and President Barack Obama has someone picking out his clothes so he doesn't have to waste brainpower on such mundane tasks.

Still, he said his No. 2 Sheryl Sandberg does make fun of his sparse wardrobe, but at least he has multiples of the same shirt. It is not the same grey T-shirt every day.

Zuckerberg also faced a lot of questions about why businesses are reaching fewer fans with their posts. The CEO said that diminished reach was because of increased competition for space in the News Feed—the average user could potentially see 1,500 posts from friends, but only have time for 100, he said.
