Dotspotting.org is online.
Had you heard about this ?.Dotspotting is the first project Stamen is releasing as part of Citytracking, a project funded by the Knight News Challenge.  We're making tools to help people gather data about cities and make that data more legible. Our hope is to do this in a way that's simple enough for regular people to get involved, but robust enough for real research to happen along the way
