"In the favelas, or slums, of Rio de Janeiro, Brazil, unnamed streets meander through the hillsides. There are hospitals, coffee shops and restaurants, none of which appear on a map, and mail carriers struggle to get letters to homes without addresses. A new project by Rede Jovem, a Brazilian nonprofit that loosely translates to "Youth Net," seeks to change that. With the help of five young "wiki-reporters" and GPS-equipped mobile phones, the nonprofit is building a map of five Brazilian favelas: Complexo do Alemão, Cidade de Deus, Morro do Pavão-Pavãozinho, Morro Santa Marta and Complexo da Maré. By uploading information to the phones, the reporters are mapping the unmapped, one road and cafe at a time." - Ozgur Uckan from Bookmarklet
