Opportunities for storing information are radically expanding - Kryder's Law states that memory capacity doubles every two years. The contents of the Library of Congress - the largest library in the world - can fit onto 125 iPods.

The management of this information explosion is critical to the future of trust and reputation. Virtuous circles can emerge as information is used to create trusted knowledge e.g. Google's search engine success. Vicious cycles can also result if we become concerned about how our information is being used. For example, Google has now patented psychological analysis of online gamers for more targeted advertising. Some consumers may welcome tailored services - such as an ad for pizza popping up on screen after a marathon gaming session. Privacy campaigners, however, are much more alarmed about such uses of information.
