To protest SOPA (Stop Online Piracy Act), Wikipedia, Reddit, Boing Boing and other sites are shutting down for a day on January 18th. The blackout seeks to educate the public about SOPA, which opponents say will "break the internet." As hard as it is to go a whole day without Reddit or the cute animals of the Cheezeburger network, the site participating in the blackout with the biggest impact is likely to be Wikipedia. Tens of millions of people around the world check Wikipedia daily for fast information for free. Wikipedia founder Jimmy Wales warned students with a tweet: "Student warning! Do your homework early. Wikipedia protesting bad law on Wednesday! #sopa." As the backlash against SOPA continues, Congress actually announced that the bill will be shelved. However, activists are adamant that the blackout will go ahead, in case SOPA makes a comeback, either on its own, or as PIPA, or the Protect IP Act.
