That still strikes me as highly silly. I mean people have always been afraid of missing out. From the tabloids, gossip, to the land-line era complaints about teenagers and phone bills. It is at most a slight exacerbator with the information flow in a similar way to group think and selection biases.
It's the dose, not the substance, that make the poison.
Because of the smartphone, social media is always with you, everywhere you go, and there is infinite content. That makes it pretty different from all the types of media that came before.

Ignorance is bliss. If I don't know you are enjoying something, then I won't feel I am missing out on it.
Since folks tend to post the highlights reel of their lives on social media, we see all the fun things and compare to our own and then feel a pang of envy or regret.
