Facebook's target audience is primarily college students. It's only more recently that it has added features which seem more highschool geared. And your an idiot if you accept random people's friendlist invites. To even view a persons profile you have to accept a friend's invitation, that is unless you chose to have your profile show publically.

Remember everyone, on the interwebs men are nerds, women are men and children are undercover FBI agents

36 year old fundamentalist Christian near Seattle, WA - I like facebook. it is not sleezy like myspace.is. my very young teens have not been approached by anyone inappropriate, but they know what to do if they are.
