Obama went beyond the somewhat static Web pages of most past campaigns, by tapping the power of Web 2.0 tools including Facebook, YouTube, blogs and discussion boards, to create a conversation with potential voters. Republican opponent John McCain used some of the same strategies, but many Internet experts saw the Obama campaign as the ultimate example of a politician embracing the Web.

"Obama's campaign created the textbook of how to do online campaigning," said Alexis Rice, creator of and a fellow at the Center for the Study of American Government at Johns Hopkins University. "Every campaign, from now on -- Republican, Democrat, independent, local level, national level, state level, will look to the Obama campaign as a model of how to do it right."

Some dissenters say that McCain and fellow Republicans made use of many of the same social-networking tools, but Obama may have gotten more credit because young voters attracted to him were predisposed to using Web 2.0 applications.

Others suggested that Obama's use of Web tools during the campaign may have been groundbreaking for politics, but his campaign made use of Internet tools that have largely been around for years.

"I am actually rather annoyed with the rosy press that the Obama campaign's technology use has gotten so far, because it is vastly underselling the full potential of Web technology for the federal government," Chris Townsend, an innovation management analyst at Forrester Research, said in an e-mail.
