I'm not sure
Well there you have it. I'm one of the 6. Joyce calls it FaceMail. At one point, when I was still living at home, I spent a couple of hours trying to teach her to check email. She might still be able to do it, but that's all the time I could commit to spending on that one task. She's not so captive an audience. Needless to say, she's not on Facebook. I'm surprised, I guess, that so many moms are.
So...does this mean I need to get Joyce on Facebook? Nah. Some things are better left alone.
