Disagree. Currently helping run a summer camp with lots of < 18 year olds where we try to limit phone usage in group sessions. Snapchat is used for everything, probably sexting too, but as far as I can tell it's the goto instant messaging. When they're on their phones during sessions, they're all snapping each other. Insta is also ubiquitous - aside from following people, lots of them use it to discover smaller/niche bands (eg grime), for example. Facebook? Really uncool. Their parents are on Facebook. Big component of these apps is the group dynamic. Plays well with the current culture of social capital, messages can be easily broadcast, rated, commented on, shared around. But you also have the option of things being semi-ephemeral.
