Topic Proposal: Facebook is Unsafe

Facebook is now a site used worldwide.  Where it began as a social networking site for college students, it is now open to anyone with an e-mail account.  Users can share a great amount of information on the site without realizing or considering who this information is available to.  Teachers, parents, employers, and even complete strangers may have access to what information is posted by or about a user.  This is a very unsafe aspect of Facebook.  Without the proper knowledge and use of privacy settings users are putting themselves and possibly their futures in danger.
