Jakob Nielsen is a respected usability expert whose research has focused on all aspects of web usability, including how people read online content. In his Alertbox column (http://www.useit.com/alertbox/), Nielsen has reported on research showing that people with low literacy “plow” through online content, reading it one line at a time.
