> I do accept that there is a generational divide in social. I don't. I think a lot of the issues can be chalked up simply to age. Today's 20-year-olds are not going to change generations. But in 20 years, they will be 40, and I expect that they will act a lot like today's 40-year-olds when it happens. When you're 20, you don't have a lot invested in the world. You have few assets, no children, etc.; you don't have a lot to lose. If some random person barges into your life, then there is a good chance that person has something to offer you. And if they don't, then there isn't much they can take away from you. But when you're 40, you probably have kids, some assets, some property. And you've learned that the random person who barges into your life, is probably trying to rip you off. And they can seriously damage you if they do. That makes you much more protective of the entrance to your social circle, and much more wary about marketing of any kind. Furthermore, for older people, life revolves around family much more. Keeping a family going, raising kids, etc., take a lot of time and work. That means you probably don't have so much time -- or desire -- to interact with huge numbers of people in a cloud-ish setting. But when social stuff meets the needs of older generations, then they're happy to use it. I thought we all knew that Facebook is quite popular among 40-year-old moms. (By the way, FWIW, I'm 45. Also, I'm not a mom, but I am a dad.)
