Nope. Here's a difference: My parents never signed up for MySpace. It takes a lot of momentum to stop a beast as big as Facebook. MySpace was never even close.
On the other hand, I'm a parent and I signed up before my kids even knew FB existed. My parents have not signed up, and likely never will. Neither will my parents parents, but then Im not sure they even know what a "facebook" even is.
I have since closed my facebook account. Unless places like here are some how called "social", I don't do "social" at all. Well, I do, but I don't call sitting in front of a computer social. I call it giving over personal information so a web site can make money. Not that there is anything wrong with that, its fair enough for those who want to partake. But to me, that is what it is. I communicate with friends via email if I have to use a computer to do so.
