Belated birthday

I just spent an enjoyable chunk of the day listening to the podcasts from Berkeley/Santa Clara's Copyright at 300. PDFs from many panelists are available along with mp3s of the panels. Many intriguing ideas about historical and modern copyright. Leaving out many, many others, Jules Sigal of Microsoft was particularly interesting on nongovernmental formalities (including things like YouTube's Content ID system); you can get a basic idea of his presentation from the PDF.
