What is participatory journalism?

CyberJournalist.net asks: "What is participatory journalism?" and provides links to answers as well.

Newsday published photos this weekend of Billy Joel's Long Island automobile wreck shot by the person who helped the rock star from his car. Some might consider this participatory journalism. Of course, readers have been selling photos to newspapers for generations, so participatory journalism, in this sense at least, is nothing new. What's new is how the Internet has expanded the outlets for participatory journalism and thus helped it spread in so many new ways.

Here's a definition of participatory journalism from J.D. Lasica:

(1) Audience participation at mainstream news outlets.

(2) Independent news and information Web sites.

(3) Full-fledged participatory news sites.

(4) Collaborative and contributory media sites.

(5) Other kinds of "thin media."

(6) Personal broadcasting sites.
