So I'm on the border between the Millenials and Gen X.
One generation gap that has often struck me on DU - the bellyaching about technology, and oh noes kids don't play outside anymore because they're inside on the computer, and no one talks at dinner because they're all on their phones. Facebook and Twitter are silly and stupid and for egotistical people to tell everyone what they had for lunch.
The phones that we use to livestream protests and take videos of police brutality. The computer that we use to access Facebook and Twitter to connect with activists all over the world, so that those videos of protests and police brutality are seen worldwide so that there are signs in solidarity with Wisconsin and Oakland in Egypt, so that in Libya they chant "Syria we are coming for you! Bashar you are next!", so that all the occupations worldwide are linked together and you hear "New York is Oakland, Oakland is New York!"
So yeah. Those paragraphs about the car and the radio and everything - easily applied to the internet and cell phones today.
Oh! Forgot one more thing I've noticed.
It tends to be the older people who are focused on leaders and personalities. People who grew up with the internet - we are Anonymous.

We're not so much into leaders or personalities. The younger crowd on Twitter doesn't care about Michael Moore, about Rachel Maddow or Keith Olbermann, about Obama. We're doing it for ourselves, and we only need us.
