Think about it. Look around. I bet there are numerous copyrighted excerpts or photographs on your site. The Stop Online Piracy Act (SOPA) and its Senate companion, the Protect IP Act (PIPA) purport to stop internet copyright violations. "But I only engage in fair use!" you say. Never mind. These overreaching laws will grant government take-down power over your site on their word. Are telling me that this power will not be politicized? We're all Gibson Guitar now.
