“[T]he critical thing to recognize […] is that the legal code is not free culture – you are free culture. The legal code is just the ‘plumbing’ of free culture, it’s code”. 

In the plenary session of Wikimania 2006 Lawrence Lessig explains his notion of the difference between “read-only” and “read-write” cultures. Subsequently he addresses Creative Commons and the above mentioned idea of legal code as foundation – as the “plumbing” of free culture. Most importantly might be the statements of bringing the licences Creative Commons and Wikipedia’s GNU Free Documentation License closer together to provide people broadest possibilities.
