As I mentioned in another comment, joining Facebook is something that just isn't a good idea for young people. The network that is praised as the primary reason Facebook is successful in the article, does more damage to someone's future than gives them benefit in the present. Schools and Colleges running checks on Facebook for anything negative about them, finding one student and following the network for other, has affected some of my friends. As has employers and work experience checking Facebook. 'The Network' also means that family are suggested to friend you almost immediately; I don't need to explain the problems with that. Snapchat is a safe haven for creative, throw away content that isn't indexable, searchable, doesn't have a social graph or a permissions model.
