A service that allows you to geotag things for your municipal government to fix: pot holes, poison ivy, graffiti, car accidents, dangerous trees, etc. This automatically creates a to-do list online for everyone to see, and lets people with an @town.state.gov email address check items off as they get done. Things like downed power wires would be submitted the same way and then automatically routed to the relevant authority.
I'm working on another project already, but if someone else wants to make this then I'll be your first user.
i think this is a great idea. Think of a mix between Digg and a Google maps mash-up. Each town or city has its own area in google maps highlighted. You can make icons for each problem that signify what it is, like a pothole, (small, medium, giant meteor crater sizes), trees, problems with power or water, missing signs, etc. People can add them where the problems are. Then people can vote on what they'd really like to see fixed the soonest by clicking on the icon. It really connects people to their government. If people invest the time to point out a problem, they're going to be really annoyed if it doesn't get fixed, and care more about who in government is not getting it done.
