I guess I have a fundamental disagreement with the idea that children are doing anything differently now with regards to the transmission of children's culture than they did before.

When I was a child, we had a very rich playground culture (As I mentioned before, I'm 45). And yet, I never heard the examples that have been given as an indication that playground culture used to be a bigger part of childrens' experience.

Secondly, my son had an extremely rich playground culture with his friends. It included things I hadn't heard when I was a child, some of which are very old, apparently, such as "Little Bunny Foo Foo", and some of which are more recent inventions.

I think the people who think kids culture has become any less vibrant or valid than it once was are selling the kids of today short.
