From Facebook, answering privacy concerns with new settings

[Commentary] Six years ago, we built Facebook around a few simple ideas. People want to share and stay connected with their friends and the people around them. If we give people control over what they share, they will want to share more. If people share more, the world will become more open and connected. And a world that's more open and connected is a better world. These are still our core principles today.

Here are the principles under which Facebook operates:

• You have control over how your information is shared.
• We do not share your personal information with people or services you don't want.
• We do not give advertisers access to your personal information.
• We do not and never will sell any of your information to anyone.
• We will always keep Facebook a free service for everyone.

Facebook has evolved from a simple dorm-room project to a global social network connecting millions of people. We will keep building, we will keep listening and we will continue to have a dialogue with everyone who cares enough about Facebook to share their ideas. And we will keep focused on achieving our mission of giving people the power to share and making the world more open and connected.
