WordPress Blackout against SOPA and PIPA
Like Wikipedia, another website that gives a content management system called WordPress.Org blacks out because of a protest against Stop Online Piracy Act and Protect IP Act.
Sites like reddit, twitpic.com, icanhazcheezburger, and many others were planning to have a blackout too for protest against SOPA and PIPA.
