President Barack Obama
American President Barack Obama has made history in more than one way. He became the first African-American to hold the highest office in the United States by defeating John McCain in November 2008, and he became the first President to actively use the Internet and social networking Web sites in his campaign. After the election, most people probably thought that President Obama's days of social networking were over. That all changed on March 26, 2009, when Obama sent a tweet about answering questions about the economy. The message included a link to the White House Web site where a video of President Obama urged Americans to write in with economic questions that he would try to answer the following day.
President Obama was much more active during his campaign, and since he took office he hasn't done a lot of twittering. He has his hands full trying to right a sinking American economy. That doesn't stop people from signing up to follow him, though. In April 2009, the President had nearly 1 million followers on Twitter [source: Twitter]. During his campaign, he (or more likely an aide) twittered almost daily about where the campaign was traveling or other helpful links. No one can tell whether his embrace of social media made a difference in the election, but it's a great way to make sure people stay connected. On Nov. 5, soon-to-be President Obama twittered, "We just made history. All of this happened because you gave your time, talent and passion. All of this happened because of you. Thanks."
