When I first read that the Wikipedia blackout was happening, I wished that I could just pull a up lawn chair on the Wikipedia homepage and spend the day watching the bewildered faces of everyone who had no clue what was going on as they lashed out in anger, fear, and frustration. Now, thanks to @herpderpedia, I can. And so can you.
The bad news is that while SOPA may be "shelved," PIPA is still on. The good news is that while PIPA may still be on, Jimmy Wales has come out and announced that Wikipedia's anti-SOPA, anti-PIPA blackout is on too. The decision isn't unilateral, but rather by concensus of the Wikipedia community and as such, the English language Wikipedia will be going dark on January 18th from midnight to midnight EST reaching an estimated 25 million users globally. Better listen to what Jimmy says and get your homework done ahead of time.
If you go to Wikipedia in the next couple of days and don't see anything, there probably isn't anything wrong with your Internet connection. Wikipedia founder Jimmy Wales is considering blanking out all Wikipedia pages in protest of SOPA, a bill that countless Internet-based content providers and freedom of information advocates are particularly wary of. Wales pitched the idea to the Wikipedia community and feels that a blackout could send an extremely powerful message to law-makers.
