I am an assistant professor of journalism at Northeastern University in Boston, Mass., and a longtime media commentator. I write a weekly online column for The Guardian and appear on the media-roundtable program "Beat the Press," on WGBH-TV (Channel 2). I am currently working on a book about community news sites.
