At Facebook, 60% of teens use privacy controls compared to 25-30% of adults, a sitepoint blog cites Facebook numbers as showing. Computer Associates offers some confirmation with a recent study finding that "79% of teens aged 13-17 who are members of a social networking site like MySpace or Facebook protect their profiles from the general Internet in some way (i.e., only allow friends or friends of friends to view their information), according to the blog. The study also found something not so surprising: that teens "are very likely" to post photos of themselves online. That may be why they're more careful about privacy. Good news!
