Authored by Market Sentinel, Onalytica and immediate future PR, the white paper usesthe example of blogger Jeff JarvisÂ's criticism of the computer retailer, Dell. Itshows first that Dell has sustained long-term damage to its brand image and secondlythat the cheerleaders for the poor reputation of DellÂ's customer services, arebloggers.
 Bloggers have extended their influence from dominating negative perceptions of Dellto dominating perceptions of DellÂ's entire reputation in the customer servicesarea, says Flemming Madsen from Onalytica.
He continues,  Bloggers used Jeff JarvisÂ's shorthand  Dell HellÂ' to collaborativelyspread negative comment about DellÂ's customer service: weakening DellÂ's reputationwhere the company used to be so strong.Â
The white paper uses the science of citation indexing: applying maths to calculate awriter's authority in a particular context and producing an index of dominantauthorities. This is familiar in academic use, but is here applied to the web forthe first time. The analysis demonstrates how bloggers exercise their power and howtheir authority has come at the expense of the conventional media sources such asthe Washington Post and The New York Times.
According to Mark Rogers, CEO at Market Sentinel, measuring the influence ofbloggers is often based on subjective opinion and rough gauges based on comment andGoogle rankings.
He says,  We wanted to take a scientific approach  objectively demonstrating whichbloggers have authority and an ability to affect corporate reputation. Using thescience of citation indexing, and the Dell case study, we are able to quantify andanalysis the impact each blogger has on a companyÂ's brand image and analyse theindirect influence as well as direct impact: proving that blogging has a significantaffect on reputation.Â
