> It's long overdue to bring copyright law into the 21st century with one small tweak: legalize noncommercial copyright infringement.

What is "noncommercial"? For instance, if I post the complete text of a someone else's book on Facebook or Reddit or in a blog at Wordpress.com, is that noncommercial because I am doing this on my personal account and get no money from doing so? Or is it commercial because those are commercial sites that monetize visits to their sites by showing ads?
