Facebook CEO admits calling users 'dumb'

Zuckerberg says he's "grown and learned a lot" since then

Facebook founder Mark Zuckerberg admits to the New Yorker that he did indeed once call   users of his popular social networking website "dumb f***s."

But the now-26-year-old says he's "grown and learned a lot" since bragging to a friend via Instant Message (as first published by Silicon Alley Insider) while still in college that he could get any information he wished on any member of the Harvard student body.

Says Zuckerberg now to the New Yorker, "If you're going to go on to build a service that is influential and that a lot of people rely on, then you need to be mature, right?"

"I think a lot people will look at that stuff, you know, when I was 19, and say, 'Oh, well, he was like that... He must still be like that, right?'" he added

There may be more unpublished IMs that are damaging to the Facebook CEO, sources tell the mag. Jim Breyer, who runs the venture capitalist firm that serves as Facebook's largest outside investor, says, "He is a brilliant individual who, like all of us, has made mistakes."

While being interviewed for the story, Zuckerberg defriended Aaron Sorkin, the screenwriter of "The Social Network" (out October 1). When called out on the move, Zuckerberg added him back as a friend.

Sorkin has said the movie, which stars Jesse Eisenberg and chronicles the launch of Facebook, "is not meant as an attack." But he admits Zuckerberg comes off an "antihero" for the first hour-and-55 minutes, "and the last five minutes as a tragic hero."

Zuckerberg has said he does not plan to see the film.
