“Research suggests the best solutions for improving discourse may come from getting to know each other as whole people instead of just opinions — something Facebook may be uniquely suited to do.”
I don’t understand how is Facebook positioned to help? You don’t get to know whole people by staring at a screen. I’m certain that’s proven; your online self is not your whole/complete/full self. You get to know people by talking face-to-face, in the physical world.
