They also plan to stream Obama's speech online tomorrow night and via their new iPhone app.
"Of course, many Americans will react to the speech with questions, comments, and concerns," Macon Phillips writes at WhiteHouse.gov. "Now we are excited to announce how President Obama will also be using the web to offer the public a direct and participatory way to communicate back to him."
YouTube will stream the speech live here, and then people can submit questions. Users can vote the questions up or down and Obama will answer them next week.
