What would really be the reaction if, in protest over - lets say legislation written by lobbyists from Silicon Valley that would make any variation of SOPA illegal - the big media companies had a one day blackout. Why aren't they considering this? Would people flip out because the new episode of Jersey Shore was supposed to be on? Would they understand the motivations and join in protest by contacting legislators?
