With all the Oculus news, Facebook has reached a crazy milestone with 1 billion mobile users. This is 1/7 of the population on the planet! It's amazing to hear that 20% of the time that is spent with mobile apps are spent with Facebook. I'm guessing this is through the Instagram and WhatsApp apps as well. Facebook has a lockdown on mobile, that is for sure. How much time do you spend on your mobile Facebook application?
