every parent has that excuse. did you know americans spend more time on facebook than they do on any other website? facebook accounts for 12.3% of time spent online in the u.s. which is gigantic. what will poor sasha and malia do with their spare time? professor, should kids go on facebook? yes or no, go. no, they should not be on facebook before they re 13. anyone can go in and kind of lie about it. i spoke people lying online? no, that will never happen. here s the problem is parents are signing up with their kids and encouraging them often under 13 and letting them do it. so why would you have your first connection with something they re going to use for the rest of their lyes perhaps be a lie? and parents who won t let their kids drink or do other things think starting before 13 is
