What would I do on it? I have zero interest in social media content, where everyone constantly posts that their ear itches, they heard a gunshot on 3rd street, or they took a dump.
Now there are more important things, like how did my brother's family vacation go, or a picture of my Mom in the recovery room.
Those items, my family shares via text, Photos, email, etc. They know at least 2 of us don't use social media so they loop us in in other ways.
Social media makes its users devalue face to face contact, suffer delusions about who their friends are and how everyone else's life is going, increases jealousy and enviousness, decreases self esteem, encourages people to live in an alternate reality and compete with each other rather than enjoying life. It increases and deepens gossip (and gossip's effects). It reduces people's real social skills, meaning in the physical (real) world.
I see it over and over, if I ever question my decision not to use them, I just listen up and pay attention to the conversations around me - it always reinforces my decision. People alternate between high (as on a drug) and miserable because of their social media. There are rehabs to get off of them. People "swear off" them constantly, but go back as if to heroin.
Now, I'm sure there are a few people who can withstand all those negative effects. Good for them. They are the 10%, but 100% of social media users believe they are them.
I don't believe I'm in that 10%. Rather, I'm quite sure it would have its typical negative impact on my life - and worse, I'd suffer the typical delusion that it was adding value to my life, which is also typical to people in active addiction of any kind. (A detached 3rd party can see the net self destructive nature of it, but the user has themselves convinced it adds a net value to their life).
No thanks, social media has almost killed a generation of kids, I'll stay away from it - and I encouraged my kids to severely limit their use of it.
PS - I'm sure I probably opened an account, but it was a temporal urge about 15 years ago when I wondered if I could "find" someone I used to know. It's not active and never has been.
