Thank you for the clarification .

By your definition I have never joined nor participated in social media. There's never been a draw for me. Like others have mentioned, family and friends who live overseas can email me, phone my landline or just snail mail me.

I find the idea that you can locate friends from childhood interesting. My family moved a lot when I was a child and I had changed schools several times even before high school. It would be nice to see how some of those kids are doing all grown up - but I was always the 'new kid' so I doubt they'd remember me anyway. Also I would inviting so much bad into my life for so little good - that does not seem worth it to me.

I can see how Facebook and the like work for people with large extended families, and for social butterflies and extroverts. But it seems to be a destructive force in the lives of a lot of people.

I often encounter people who are on Facebook who seem to have several things to be outraged about each day. Things they would not know about otherwise. So Facebook also seems to be good for people who are addicted to outrage - something this little peace - loving introvert does not understand.

TL;DR version: I've never been a part of social media, as the OP defines it, and that seems like a good decision for myself.
