roll of social media

KL
I tried to make this the poll, but polls are so limited... It didn't work. 
So, here's my question. Is social media (and all the over sharing) a reflection of the "all about me" mentality or were people always like this any now it's just more apparent?
It's things like people wanting to be "instagram famous" and fighting for followers and putting EVERYTHING about your personal life online. Anything to be in the spotlight because I AM SPECIAL and IT'S ALL ABOUT ME and people HAVE TO accept everything I do, think, and say. 
So before you tell me social media is perfect for sharing baby pictures with your brother across the country, that's not what I'm talking about. I'm talking about people who use it as described above.
