James Kotecki, Private Citizen
Although he doesn't have his own Wikipedia entry any more, James Kotecki did have a noteworthy career as an Internet celebrity, which began with critiques of candidates' use of YouTube from his Georgetown dorm room and concluded with his last daily webisode for Politico.com. During his two years of Internet fame, he promoted participation in the CNN-YouTube debates and was profiled in several major newspapers.
Last Fall Kotecki came to my digital rhetoric class via our campus's teleconference facilities. You can see his answers to questions from students in this series of videos in which they asked him about how he sees the evolving relationship between YouTube, fake news programs on television, social networks, and politics.
