I've been a fan of Michael Wesch and his work since his first Web 2.0 video over a year and a half ago. He presented this at the Library of Congress, June 23rd 2008. I was shocked when I saw that it was 55 minutes long since most of his videos are under 5 minutes. But you know, some things are worth the time, and this is one of them.
If you work in education I think it's especially important to understand that there is a digital revolution taking place. The participatory culture that so many have embraced has changed and will continue to change how we live, work, learn, etc. Watch his video below to see if you agree.
