Facebook is announcing changes today that will let people quickly know exactly who can see everything they post and to block unwanted photos and other items tagged by others from their profile page.

The company also is making a semantic modification that will eliminate a lot of confusion for new Facebook users--changing "everyone" to "public." Currently, many people think that setting their sharing to "everyone" means everyone on the social-networking site, when it actually means "everyone on the Internet."

Overall, the changes make it easier for people to understand what audience will be seeing what they post on Facebook and to control who sees what others post that refers to them. The changes will start rolling out in coming days and people will be prompted with a tour option when they are available.
