CWmike writes: The White House will be tapping Web 2.0 technology to reach out to Americans during and after the president's State of the Union address tonight. While President Barack Obama makes his annual address starting at 9 p.m. ET, the official White House Web site will have a live stream of the speech, along with charts and statistics to provide context and emphasize key points. 'We're putting the finishing touches on a new feature for WhiteHouse.gov that will offer an enhanced viewer experience for President Obama's State of the Union address," wrote Macon Phillips, the White House director of new media, in a blog post. Immediately after the State of the Union address, the White House will host an Open for Questions event on Twitter. Several senior administration officials will be fielding questions submitted on the White House Facebook page , the White House Webform, or via Twitter using the @sotu hashtag and responding to @whitehouse. And on Wednesday, Press Secretary Robert Gibbs will take citizens' questions via Twitter before his post-State of the Union briefing. Anyone interested can follow @PressSec on Twitter to find out when Gibbs will take questions and post video responses. To submit a question for him, respond to @PressSec using the hashtag #1Q. At 2:30 p.m. Eastern on Thursday, Obama will take questions live on YouTube.
