Jay Rosen teaches journalism at New York, where he has been on the faculty since 1986. From 1999 to 2005 he served as chair of the Department. In 1999 Yale University Press published his book about the civic journalism movement, What Are Journalists For? Rosen is the author of PressThink, a blog about journalism and its ordeals in the age of the Net (http://www.pressthink.org), which he introduced in September 2003. In 2006 he founded New Assignment.Net, his research vehicle for open source journalism projects. In 2007-08 he was co-publisher, with Arianna Huffington, of OffTheBus.Net, an experiment in pro-am election coverage that eventually drew12,000 participants. On Twitter Rosen coined the term “mindcasting” to mean a style of sharing links and connected thoughts, in contrast with "lifecasting." He is found at http://twitter.com/jayrosen_nyu
