We're off for the day celebrating the birth of our nation, but we wanted to leave you with something today ... just in case you are chained to you desk.

This week, we were lucky enough to see Kansas State University professor and anthropologist Michael Wesch's presentation about YouTube and Internet culture at the Personal Democracy Forum. Wesch rose to prominence in the YouTube community thanks to a short video he made in 2007 called "The Machine is Us/ing Us." While we wait for someone to post a high res version of his presentation from Tuesday, here is a similar presentation Wesch did last year at the Library of Congress. It's long, but its worth it.
