I wonder what took these two tech giants so long to realize they should have taken the 1st page off mobile users. With this move, facebook will completely integrated into mobile user behavior. One of the few things in the journey of a mobile user definitely includes navigational properties and with the ease of always having the app with you no matter where you are on your mobile screen makes it exceptionally habitual. I say this is a great move that took Zuck a tad too long to have it up.
