no twee-tin, no Facebook, no what's-app, or what ever else they are called, I have a full life and no time to stare at social media to see cats on rumbas or latest stupidity people post about themselves their neighbors or what not, I know what's going on the world by watching 4 World wide news (BBC, RDI, France24, Al Jazeera) cast in the morning before work and NPR in the car on my way back to the house.
if I need to talk to someone, I call them on my phone. I do plenty of Texting and Emails in a day for my IT work (traveling technician) that I get home, the phone goes down, its set for "leave me alone" mode from 6pm-4am unless on my emergency list of phone numbers (friends and family only).
who needs Facebook to know someone is upset because of the politics, why does my 24 year old nephew only works 2 days a week in a bar, and plays video games the rest of this days... my best friends daughter got a new daughter, my 84 year old mother in law is on her death bed, my 82 old Mother rocks the bowling alley on weds.. lol I don't need an app to tell me what's going on around me, I speak to my peers, and listen to the stories they bring to me over coffee or beer and sometimes, a little too much wine, besides its makes for good laughter.
I do I guess socialize online, sometimes, when I want to scratch some records and Dj some music in a 3d world called Second life. but that doesn't happen often... (been 3 months since I Dj'ed online)

Note: I think you will find most over 50 do little of those social things like the 20-35 groups does all the time...
