Proof the SOPA Blackout had a political impact.

Hi, I’m Barack Obama, President of the United States. Ask me anything. I’ll be taking your questions for half an hour starting at about 4:30 ET.
Proof it's me: https://twitter.com/BarackObama/status/240903767350968320
We're running early and will get started soon.
UPDATE: Hey everybody - this is barack. Just finished a great rally in Charlottesville, and am looking forward to your questions. At the top, I do want to say that our thoughts and prayers are with folks who are dealing with Hurricane Isaac in the Gulf, and to let them know that we are going to be coordinating with state and local officials to make sure that we give families everything they need to recover.
