Those childish comments are so funny. 3 billion people use Facebook regularly, and there are folks that deem themselves superior to all others who claim "I know nobody who uses Facebook". XD
“It’s not a childish comment in the slightest, and most definitely not a claim of superiority in any way either. It’s simply a fact. I, too, know a grand total of 0 persons who use Facebook. Three billion people may use it regularly but all the people I know are in the other, let’s say >vast majority<, of FIVE billion people who don’t even care about Zuckerberg’s billboard.”
