Many sites like Google and Wikipedia are blacked out today in protest of the SOPA and PIPA bills. Many individuals are “taking action” by blacking out their Twitter avatars. If you want to do something productive to protest SOPA, and you’ve already called your local representative, you should write, draw, paint, photograph, record, publish, or make something wonderful and share it under Creative Commons license.
Media corporations have control over their copyrights and have the lobbying power to push things likes SOPA and PIPA through Congress. Changing your Twitter avatar won’t stop that. What you do have the power to do is create wonderful things. The more we make and share, the less in-demand are the types of media that are illegally pirated and endanger the open Internet as we have today.
