Not going to do this one, sorry. I am "anti-social media." The best thing I ever did online was to quit my Facebook account.
It's not that I don't want to be "in the know" or connected to my friends; I just like doing those things IRL (in real life).
I stay up to date by reading a lot of websites that capture the trends (Buzzfeed is a good one to see what the kids are into these days).
I stay connected to my friends by corresponding with them by e-mail, Skype, or seeing them in person.
I have a lot more opinions about it, but I'd rather have a real conversation with you about it than post it on here.
