Facebook announced some changes to the privacy settings for teen users on Wednesday. Teens' post will now be shared with a similar group of people by default. And even more problematic is that they'll also be able to share things with the public for the first time.

Facebook's changing the default share setting from "Friends of Friends" to just "Friends" ought to lead to fewer instances of teens sharing things with people they didn't want to share them with.

Will we see more embarrassing posts from teens soon?
