Word has it that Spot.us, former CJR intern David Cohn’s community-funded journalism startup, will be launching late this afternoon. An experiment with crowd-funded journalism, Spot.us encourages private citizens to fund investigative reports on topics that interest them. Freelancers can pitch ideas to the crowd and solicit donations, or readers can suggest story ideas of their own. It’s unclear how successful this will be, but it’s an interesting idea, and probably worth checking out at some point today or tomorrow.
