In today's world most people just got lazy, most people who are against SOPA didn't even contact their representative.
Yeah, the Internet does that. Anyone over 30 probably would have noticed that attentions spans of people kind of correlate with how much time they spend watching TV or web surfing.
People have access to more information, but their attention spans are split up between a mass of continuous updates and instant messages. People are more connected, yet more detached. The irony is that more information divides how much you can be pissed off about anything. Why just this? How many other things can you find that actually erode freedoms or affect them negatively, and people just let it slide after a few complaints? I've already watched on the street interviews with people on the news, and most of the people saying they are against this don't even say what it is they oppose or even know what it is they oppose.
To tell the truth the Internet is not going to become a black void simply because if this, certainly people aren't going to explode over it. Life goes on.
