Reputation Managers are Happening

After years of predicting the rise of reputation managers, they finally seem to be happening.

A reputation manager is an independent service that keeps track of the rated quality, credibility, or some other desirable metric for each element in a set. The things being rated will typically be websites, companies, products, or people, but in theory anything can have a reputation that users may want to look up before taking action or doing business.

The reputation metrics are typically collected from other users who have had dealings with the thing that is being rated. Each user would indicate whether he or she was satisfied or dissatisfied. In the simplest case, the reputation of something is the average rating received from all users who have interacted with it in the past. Other systems are possible, as discussed below.

Reputation Manager Problems

When collecting feedback from random people, the results can be random as well. Third Voice suffers from the traditional flaming problem of Usenet as well as the low signal-to-noise ratio of chat rooms. You never know whether the person who posted a comment actually knows what they are talking about or whether you are wasting your time reading some bozo's rantings.

Amazon.com pioneered the idea of customer reviews, but has been plagued by unreliable reviews (an author's enemies post a flood of negative reviews; followed by the author's friends who post glowing reviews). Also, users never know whether they can trust reviews that are posted as part of a site that profits from selling the product.

Google and eBay avoid these problems by aggregating ratings across a very large sample. Google also benefits from the fact that Web authors are reluctant to include a link unless they actually want to guide users to the destination site. Even if there are some spurious links, they vanish when doing statistics across a billion pages with several billion links. eBay collects reputation rankings from the specific people who actually bought something from a seller, thus avoiding comments from random users.

Epinions is a double reputation manager: not only does it rate products and services, it also rates reviewers. After users have read a review, they are encouraged to vote on whether they found the review useful or not. In showing lists of reviews to users, Epinions places the most highly rated reviews on top, thus assuring that readers will focus on the best content. Also, reviewers build up status depending on the user feedback on all their reviews, meaning that people will be reluctant to contribute low-quality reviews to the service. A final interesting twist is that users earn a micropayment every time somebody reads one of their reviews. Thus, people are motivated to write valuable reviews, not just to gain a high reputation rating, but also to earn money.

Future of Reputation Managers

I see reputation managers as core to the success of the Web. As we get more sites, more content, and more services online, users need a way to learn what is credible and useful. Quality assessments must become an explicit component of most Web user interfaces. It is not sufficient to list millions of items for sale and leave it to the user to determine what they need. Everybody is not equal.

Reputation managers overcome the complaint against shop bots that they purely focus on price and ignore customer service. Once it can include an independent source of rating data, a shop bot can show users:

Reputations managers will thus cause a renaissance for good customer service: the way a company treats any individual customer will be fed directly back into its reputation ranking and will influence its future sales.

Investors will finally get a handle on intangible concepts like "brand equity" and "goodwill": just go to the reputation manager and look up how customers rate the company and various aspects of its service. If a company does something wrong, its reputation statistics will rapidly drop, immediately followed by a massacre of the stock valuation. If a few Belgians become sick from drinking a soft drink, then the manufacturer may lose billions on Wall Street five minutes later. Another reason reputation managers will contribute to highly improved product quality and customer service.

Disclosure: I am on the advisory boards for Epinions and Google.
