It's good to be reminded that just 300 years ago, people didn't even have a concept of copyright. These days, copyrights are often described as natural rights founded on basic ethics, but that's just not the case. Copyrights are a set of laws that were invented by people to have certain effects on society.

I see things like these Amazon reviews for Tweet Nothings and I'm amazed at how effective the PR departments of the copyright industries have been at making us think like they want us to. Almost all of them could have been written by the RIAA or MPAA. http://www.amazon.com/gp/product/1593597770
