I recently attended the O'Reilly Open Source Software Convention, and was fortunate enough to catch Lawrence Lessig's keynote there, on the historical role of intellectual property in popular culture, and how media companies are perverting the intent of IP law. Old news for many, I'm sure, but Lessig states the case well; and the accompanying Flash presentation is worth a few minutes of your time, if nothing else.

And if you feel moved to act by his words, then by all means, do so.
