Washington - The official website of the president, Whitehouse.gov, experienced a dramatic makeover at 12 P.M. ET today, just as Barack Obama was being sworn in and giving his inauguration speech. The redesign features some of the same interactive elements that were present on Obama's campaign website, including a place where people can sign up for email updates from the President and his administration, an "Agenda" section that lists the administration's positions on major issues, and a new White House blog.
