Facebook wants to make it possible for these African kids to have their own profile picture
There's probably no way for Facebook to be satisfied with its overall market penetration when an estimated 5 billion people in the world still lack an Internet connection.
Which means that billions of people still aren't posting status updates or "liking" your food photos on Facebook.
Mark Zuckerberg, et. al., apparently found that problem so vexing that they chose a rather extreme solution: Boost the market on Earth by colonizing outer space.
