Key Value?

Marketing inside-geeks are putting it about that a new technology is being utilised on ad-bearing websites. The state of the art marketing system performs an analysis on the person browsing the site based on the speed and pattern of their keystrokes. This information is then fed back to a database application, and the user is matched to a specific personality category. This category is then used as the basis for targeted adverts on the website pages. Critics of the system claim that it's at best tricky to categorise an individual based on the way they type on a keyboard, and leaked reports of testing from back when the system was under initial development showed that it categorised anyone with a typing speed over 40 words per minute as a sociopath with a tendency to impulse-buy dairy produce.
