Not sure why investors freaked out over this news... Will it hurt Facebook 5 years from now? Maybe, but I'll get back to that. Right now Facebook is growing their revenue like crazy while daily users is still growing. Mobile revenue is now around 50% and they killed expectations. As for the decrease in usage with younger teens...luckily they bought insurance. It's called Instagram. A thriving and rapidly growing social network, which just so happens to be popular among teens. If Facebook did not own Instagram, then I would completely understand the market's reaction to hearing that. In my mind, this is just the market over reacting.
