Beginning Wednesday, the networking Web site is taking the rare step of requiring its more than 350 million users to review and update their privacy settings.
The new controls are designed to simplify the cumbersome privacy controls that have confounded many users. Facebook said the changes are based on user feedback - though it remains to be seen whether the shift will mean fewer surprises for people who have unintentionally shared party photos with their bosses.
As part of the changes, Facebook users will be able to select a privacy setting for each piece of content, such as photos or updates, that they share on the site - as they share it. The choices are "friends" only, "friends of friends" or "everyone." There is also an option to customize groups of friends for certain kinds of updates - such as "college buddies."
Jules Polonetsky, co-chairman and director at the Future of Privacy Forum think tank in Washington, praised how the process resembles the way people decide what to share in their day-to-day lives. He said putting the controls "when you need it, right there, is far better than putting it in a `privacy' or `help' location" somewhere on the site.
Facebook will be asking users to review and alter their settings through a tool that explains the changes. People will be able to either keep their old settings or take recommendations from Facebook that are largely based on how they have configured their information.
As promised, Facebook is also getting rid of its geographic networks, because many of them - take "New York" or "Australia" - have gotten too big. If users were previously part of such a geographic network, this location will now be listed in their profiles under "current city."
Other networks, for schools and workplaces, are staying.
The changes have no effect on advertising on the site, said Elliot Schrage, vice president of global communications and public policy at Facebook.
But he added that by giving users such granular control over the content they share, Facebook is encouraging more sharing and a greater connection to the site.
"If users feel more confident with our service, they will use our service more," he said. "And the more they use our services the more benefits we derive."
