Speak of the devil...Dan Gillmor, the man who has done more than any other to bring participatory journalism to the attention of the mainstream press, has bid farewell to his job in print media. He's also set up his new blog on grassroots journalism. Yesterday's post refers to the remarkable experiment in citizen journalism being conducted by the Greensboro News & Record. I'll be looking for more of Dan's historical analysis of by-the-people journalism. I'll also be looking to see if he shares my belief that the movement is about to shift away from "broadcast" issues -- politics, sports, celebrities -- and shift toward the "narrowcast" fields dominated by the trade press.
