Here at the Freedom to Connect conference in Silver Spring, Maryland, Dan Gillmor is moderating a panel about peer production news. Here are some examples:

• Bakersfield pothole map
  Locals report seeing potholes and they get mapped.
• U.S. Fatalities in Iraq
  Someone has taken the home of record for each U.S. fatality in Iraq and mapped it.
• Chicago Crime Map
  This one says down at the bottom: "Important disclaimer: This site is not affiliated with the Chicago Police Department. This site uses crime data obtained from the CPD’s Citizen ICAM Web site, which is a publicly available database of reported crime. Please read the Citizen ICAM disclaimer to understand the data fully."
• Bakersfield homicide map
  "This is a map of Homicides in the Bakersfield area that occured in 2006. Locations are approximated and based on data provided by the Office of the Coroner."

In all these cases the data are mapped by someone who is not an official data producer, and at least in the pothole map case, the actual data are produced by individual citizens.
