Alek Tarkowski, a PhD student in Poland, has started a group translation of Lessig's 'Free Culture'. They are using wiki software to develop the collaborative Polish translation (English introduction to the project here) - in the same way that Aaron Swartz has enabled users to adapt the book and add new chapters if they wish using wiki software.
This response has been incredible - by enabling users to adapt and transform the work, Lessig's work has been able to find vast new audiences who may never have learned about the ideas in the book. By enabling people to get into the machine, take it apart and build it anew, we have been able to understand it more clearly than any book that we have merely ingested as a passive reader.
How about a cc-translation wiki that people can go to to work on translations of cc-licensed works?
We'll be talking more about this on the cc-translation list. Please join.
