I don't understand this... are jobs and the source of peoples social validation not options? I used to derive social validation from drinking and kicking ass in video games, but then I found out you could get it from other places that were more productive, and less physically deteriorating.
If there are really people out there who are wholly dependent on Facebook for their social validation then that is a tragedy akin to finding out that there is an entire population of people who can't metabolize food without a special compound found only in White Castle burgers.
