Some great, sane ideas on improving copyright law [1]. The amount of resources the current copyright laws waste is surprisingly high. "For software, the direct costs every year of defending infringement suits from so-called "nonpracticing entities" – better known as patent trolls – come to more than 10 percent of total annual R&D spending by all U.S. businesses."

I've become more and more convinced that copyright laws do not promote progress of useful arts and sciences. The most obvious example is the incredible success of free and open software. Are people really going to stop writing books, composing music, painting pictures, etc, without copyright protection? Not a chance!
Automatic copyright for some reasonable time, say 10 years, could be automatic and free. Renewals past that time (E.G. in 10 year blocks) should be exponentially more costly.
