From the NYT:

You think your local water supply is polluted. But you’re getting the runaround from local officials, and you can’t get your local newspaper to look into your concerns. What do you do?

A group of journalists say they have an answer. You hire them to investigate and write about what they find.

The idea, which they are calling “community-funded journalism,” is now being tested in the San Francisco Bay area, where a new nonprofit, Spot Us, is using its Web site, spot.us, to solicit ideas for investigative articles and the money to pay for the reporting. But the experiment has also raised concerns of journalism being bought by the highest bidder.

The idea is that anyone can propose a story, though the editors at Spot Us ultimately choose which stories to pursue. Then the burden is put on the citizenry, which is asked to contribute money to pay upfront all of the estimated reporting costs. If the money doesn’t materialize, the idea goes unreported.

“Spot Us would give a new sense of editorial power to the public,” said David Cohn, a 26-year-old Web journalist who received a $340,000, two-year grant from the Knight Foundation to test his idea. “I’m not Bill and Melinda Gates, but I can give $10. This is the Obama model. This is the Howard Dean model.”
