Seems like a good fit given that people are maintaining fake friendships and fake amazing lives on their timelines. [edit] yes I am bitter from past experience.
Biggest problem on SO is the constant need by the moderators to mark a question as 'not a question', when it's actually a really question and gets a lot of good answers.
I agree, social media is creating new social disorders and providing a platform for people to knowingly or unknowingly destroy their lives. Facebook enables people to display a very skewed version of reality and enough of that in someone's social circle leads to feelings of failure, unworthiness, depression, rejection etc. So whilst this is not a disease to be cured, it is still a health issue.
