Yesterday's panel on global digital activism at the Computers, Freedom, and Privacy Conference in Washington DC, moderated by moi, was a great chance to learn about powerful examples of online organizing that aren't as well-documented or as high-profile some others. (Video is here.) One case study in particular stood out: the "Freedom Not Fear" privacy campaign that drew more than 75,000 people to the streets of Germany in 2008. The campaign is ongoing, and the keys to its success thus far, said organizer Ralf Bendrath, are a simple message, persistent photographic documentation, a great deal of humor, this Stasi 2.0 street stencil, and, yes, Twitter. (A particular favorite from Bendrath's talk: this web overlay that empowers supporters to back the cause with a few lines of Javascript code.) If you're a student of digital activism, the Freedom Not Fear example is worth a deeper dive. (Photo by fabnie)
