I recently finished reading "Free Culture" by Lawrence Lessig. The actual book from our local public library, not the freely available PDF - that site seems to be down unfortunately. Even though it is written by a law professor, the book from 2003 is a pretty good read. I wonder how depressing the time since then must have been for him, as things have not gotten any better with the presumption of innocence being totally disregarded with the increase in corporate police state like things as the DMCA Takedown notices
Copyright is a subject that has had my interest for quite a while. While at Ohio State I created a website called "CopyRight/CopyWrong" for a class I took ("Cyber Theory and Practice"). At filmschool our brilliant but pedagogically challenged professor Wim Verstappen taught us how to put the © sign in the right place and urged us to always use it. I have put it on all my work since. I am seriously considering changing that by adding the extra c and re-releasing everything under the Creative Commons license, probably CC BY-NC-SA. Stay tuned!
