In the grand tradition of the printing press and the telegraph, YouTube has revolutionized human communication­—and casually allowed its millions of users to replace “culture” with “user-generated content.” YouTube’s rebuttal to Gutenberg’s Bible and Morse’s foreboding dispatch (­“What hath God wrought?”)­ includes Doobie Brothers concert footage, local weatherperson bloopers, and girls kissing. In “The Anthropology of YouTube,” Kansas State cultural anthropologist Michael Wesch tackles YouTube’s particular cultural contributions, along with Internet partners-in-crime such as Flickr and Twitter. In the lecture, Wesch promises to explain the exponential nature of these technological advancements, whereby it took humans tens of thousands of years to start writing things down, but less than a minute to upload their cousin’s sweet skateboard wipeout video (bandwidth depending). Perhaps Wesch can also explain how modern culture hasn’t caught up to the advanced technology that supports it through these—­hey, girls kissing! Wesch speaks at 4 p.m. Monday, June 23, at the Library of Congress James Madison Building’s Montpelier Room, 101 Independence Ave. SE. Free. (202) 707-2692.
