My oldest got me started on FB, she was in college, I was a non traditional student in a Community College. Now she is rarely on FB, and I'm there daily, the youngest is on FB sporadically, the middle rarely. I don't know if any of my kids use other social media platforms.
It's one thing to keep in touch with family and friends. It's quite another to get all your news from Facebook posts of Infowars, Breitbart, Q Anon, and other stinky brain farts.
