THE OBAMA campaign made the most of a range of so-called Web 2.0 social networking technologies that are particularly popular with the 20- and 30-year-olds who were some of the president-elect's initial, ardent supporters.

The Obama website, created by personal profile site Facebook co-founder Chris Hughes, was considered a showcase and a model for using such technologies, but internet and mobile users connected to the campaign off-site as well.
