To the very end, Barack Obama's campaign made use of the power of getting people together through the Internet.

Just before he headed out to claim victory at a huge rally in Chicago's Grant Park, the President-elect gave a heads-up to his tech-wise supporters. Those who had signed on to his Web site got an e-mail thanking them -- and letting them know he was about to address the nation.

The message said he was headed to the victory rally but before leaving he wanted to thank his supporters who were online. Obama told his backers: "We just made history." And he thanked them for knocking on doors, making donations and talking up his campaign.
