(CNN) As Facebook continues the slow rollout of a tool to let users search out others by using common interests or other personal information, the site emphasized Thursday that minors will get special privacy protections.
Graph Search capitalizes on Facebook's massive bank of data about its users, or "social graph," to seek out friends, or other users who have made their information public, using information about them.
So, for example, you could seek out friends who "like" director Quentin Tarantino to make an invite list to see "Django Unchained" Friday night or remind yourself which of your friends are over 21 and live in Austin, Texas, to do some bar-hopping while you're in town.
But privacy advocates are worried. While Graph Search won't show you any information that you couldn't see otherwise, it does pull all that data together in one place in a way that could have some creepy uses. Say, searching for the names of girls who attend a certain middle school.
