The big change took place in the law, not the technology. The Bush people managed to keep Bill Bradley's campaign with linking to friendly web sites in a web ring by complaining to the FEC through lawyer Ben Ginsberg. But that faded later in the decade, when it became clear that Web sites run by third parties, and web comments made by people outside the campaign, were free speech.
Meanwhile the Dean campaign of 2004 failed to "scale the intimacy" of its blog when everyone rushed to the rail, resulting in an orange-hatted mess in Iowa. One result was that the Democratic clubhouse moved to the Web site of Markos "Kos" Moulitsas, who had recommended the switch from a blogging to a community network service (CNS) platform.
