I don't think so. I joined facebook back when it was 'cool', but it's not just my generation that are now adults that are on there. My parents, my friends parents, adults in their 50/60s+ have all joined facebook and are very active despite not being on there when it was only used by college students. Part of the reason why many younger people are no longer as active on Facebook is because anyone from their boss to their aunt to their grandma is now likely to see their posts.

Oh my! Thank you, thank you, thank you. It annoys me what parents think they can do with/to[0] a child just because they're the parents.

[0] I'm firmly against ear piercing a child, for example. Parents, those are not your ears to poke holes in.
