Facebook has become such an important aspect in people's lives, that increasing number of employers, and even some psychologists, believe people who aren't on social networking sites, could be insane.
German magazine Der Taggspiegel went so far as to point out that accused 'Dark Knight' shooter James Holmes and Norwegian mass killer Anders Behring Breivik have common ground in their lack of Facebook profiles.
Also, Forbes.com reports that human resources departments across the country are becoming more wary of young job candidates who don't use the site.
Bosses believe that a lack of Facebook could mean the applicant's account could be so full of red flags that it had to be deleted, the Daily Mail reports.
Not only this, another website Slate.com's tech reporter Farhad Manjoo wrote in an advice column that young people shouldn't date anyone who isn't on Facebook.
"If you're of a certain age and you meet someone who you are about to go to bed with, and that person doesn't have a Facebook page, you may be getting a false name. It could be some kind of red flag," Manjoo wrote.
According to the paper, some psychologists believe that using Facebook in today's modern society has become a sign of having a healthy social network.
