One of the founders of Facebook says even he doesn't want his friends to know what he's up to all the time.
"Most of the time I don't want all of my friends knowing exactly where I am at every moment and exactly what I'm doing," Chris Hughes told a business lunch in Montreal on Tuesday.
That admission may come as a surprise to privacy advocates who have attacked the social networking site for how it handles the personal information of its users.
Recently critics have accused Facebook of continuing to track users' browsing habits after they have logged out of the site. Mr. Hughes did not address the criticism directly in his speech.
But he did argue that social media shouldn't replace old-fashioned human contact.
"I want to continue to live in a world where people can get through a meal without looking at a phone," he said.
"I want to have days when I only spend a little bit of time in front of a screen."
Mr. Hughes was part of the small team that helped Mark Zuckerberg found Facebook. He was in charge of Barack Obama's online campaign during the 2008 election campaign.
