SeeClickFix
If you see a problem in your neighborhood, or anywhere for that matter, and want to take low-hassle but decisive action, the new site SeeClickFix might be for you. The site is a distributed sensing and community problem solving application. It is a great platform not only for citizens that want to report and track issues (and watch areas) but governments, community agencies or other groups that want to mobilize and involve their constituents.
