Story Exchange, a crowd-funding experiment piloted by Public Radio Exchange and Louisville Public Media, has garnered full funding for two long-form reporting projects: Erica Peterson’s three-part series on disposal of coal ash produced by electrical power plants, and in-depth coverage of the environmental effects of the Ohio River Bridge project, a reporting assignment that’s now in the works. PRX received a 2010 Knight News Challenge grant to pilot the project with LPM and Spot.us. PRX’s John Barth recently reported for MediaShift on the progress so far, and tentative plans to expand Story Exchange to additional public radio markets and indie producers.
