From the about page:
Geojournalism.org is made for:
Journalists
Reporters, editors and other professionals involved on the noble mission of producing relevant news for their audiences can use Geojournalism.org to produce multimedia stories or simple maps and data visualization to help creating context for complex environmental issues
Developers
Programmers and geeks using a wide variety of languages and tools can drink on the vast knowledge of our contributors. Some of our tutorials explore open source libraries to make maps, infographics or simply deal with large geographical datasets
Designers
Graphic designers and experts on data visualizations find in the Geojournalism.org platform a large amount of resources and tips. They can, for example, improve their knowledge on the right options for coloring maps or how to set up simple charts to depict issues such as deforestation and climate change
It is one thing to have an idea or even a story and quite another to communicate it effectively to a large audience. Geojournalism is designed as a community site that will help you communicate geophysical data to a non-technical audience.
I think it is clear that most governments are shy about accurate and timely communication with their citizens. Are you going to be one of those who fills in the gaps? Geojournalism.org is definitely a site you will be needing.
