I am a vain, vain person. I take it very personally when something I post on Facebook doesn't get tons of likes. I'm also addicted to Facebook, but that's a different story for a different day.

So I'm really glad that someone figured out what will get you the most likes on social media.

Hey, it worked for Geraldo

Turns out selfies do it.

Photos that include faces are far more likely to get likes, according to the survey from Georgia Tech.

On the other hand, selfies are linked to narcissism and mental illness.

So does that mean narcissistic and mental people only like things on social media?

Whatever. I'll take it. As long as they're clicking "like", it's ok with me.
