Facebook out of favor with teens, tweens
Recent trend reports indicate that teens and tweens are now (insert disaffected shrug here) kinda bored with Mark Zuckerberg's social network, flocking instead to fresher services like Instagram and Snapchat.
Sfgate.com reports part of the appeal is that parents are less clued-in to these newer tools, so they can be enjoyed more furtively.
Facebook actually warned investors of its declining cool factor recently, noting, "Some of our users have reduced their engagement with Facebook in favor of increased engagement with other products and services such as Instagram."
But before you start seeing the writing on the wall for Zuckerberg, don't forget: Facebook owns Instagram, too.
