Teenagers are still on Facebook; they're just not using it as much as they did. It was a landmark statement, since teens are the demographic who often point the rest of us towards the next big thing.
Facebook just isn't cool anymore to teenagers. Why?
Facebook is Exhaustive but Teens Don't Care
You can do so much on Facebook and teens just don't care. Apps like Twitter or Instagram are simpler and do mostly 1 or 2 things really well. Sharing Pictures and posting statuses.
You (the Parent) and every other adult are on Facebook
The popularity of Facebook is also what is turning off these young teens. This is because their parents and friends' parents are also on Facebook and get to see some pictures or videos of their teenaged children some of which the latter may want to restrict to their friends alone. There are of course settings to regulate who all see their posts, but they may not want all the posts to be restricted and so not want the settings to affect all the posts. They may then need to customize each post for who views them.
Networks such as Instagram and Snapchat are mostly student-used or teen-used services and kids don't run the risk of parents watching what they're up to.
Needs to be More Mobile-friendly
Finally, what really turns the tide of teens' actions is the fact that networks such as Instagram, Twitter and Snapchat are easier to use on their smartphones than Facebook's mobile app. Kids really prefer posting what they feel and what they do there and then which answers why they're on the mobile most of the time. Facebook falls back here a bit in its ease-of-use but it is something the social media giant can and will improve upon. A really user-friendly mobile experience would be all that's needed for teens to forget about all the other factors and start using Facebook again.
