Wikipedia founder Jimmy Wales has confirmed that the free online encyclopedia will shut down on Wednesday, January 18 in protest of the Stop Online Privacy Act (SOPA) and the Protect IP Act (PIPA), two anti-piracy bills that are currently being debated in Congress. Jay Rosen, professor of journalism at NYU had posted on Twitter, “Wikipedia Will Shut Down on Wednesday to Protest SOPA tnw.co/xRk6oc Twitter, Google, Facebook should join in.” However, this may no longer be true. Reddit, TwitPic, Mozilla and Worpress will join Wikipedia tomorrow and shut off their sites for 12 hours, while Google will feature a homepage link stating their opposition to SOPA. Other popular services like Facebook, Twitter, Tumblr and eBay have voiced disapproval of SOPA but will not take part in the blackout.
