If you have had problems with sifting through hordes of unwanted email to actually get to the email that matters, Seriosity has the cure for you. The company has developed an e-mail management system that derives from the virtual economies in World of Warcraft and other MMORPGs.
The system relies on a currency, called the Serio, that e-mail readers spend to classify messages according to the level of importance. The more important the message, the more Serio you spend on it.
[The system] was directly inspired by the virtual economies of online games like WoW. There, players accumulate gold or platinum pieces or some other form of currency and can spend them on weapons, armor, dwellings and the like that have real monetary value as demonstrated by what people will pay for them on auction and third-party sites.
Ultimately, the idea behind the e-mail management system is to manage the attention of corporate employees. According to a study by Basex, e-mail-related attention-management problems along with other online tools cost the U.S. economy about $588 billion a year. For one Seriosity client, the problem costs about $1 billion a year.
