Absolutely awesome DIY Guardian article by noted pioneer and leader in the field of data journalism Paul Bradshaw from how to source, munge, and report the facts in a coherent form from oceans of available data. Facts are sacred.
I love this article and the Guardian, who does wicked work in this area, for being awesome enough to publish it and to show people how to do it themselves. Very, very cool.
The Guardian also has an insightful how their own datajournalism work on the Afghanistan Wikileaks data went as well.
I can see so many uses for this in campaigning. Just need time and tools.
