These days, it is possible to get on any number of sites and search for an apartment in a far away city. However, what you get in these places is simply an address. It gets difficult to tell if the area is, for example, the good or bad part of town, or if it's within walking distance of the supermarket, or if the bus line that runs all night passes anywhere near it.
Enter the Neighborhood Project. The goal for the project is to provide information that allows somebody to know what amenities are in their neighborhood and provide a way for residents of said neighborhood to share their knowledge.
