Aaron Barlow, an associate professor at New York City College of Technology, wrote that "the problem with this, from a horizontal point of view, is that important work that really should be part of the education of the individual is moved to the "experts" who provide the gatekeeping. A neterate person should know how to negotiate the web for accurate information without need of a guide; providing guides may only prevent people from being fully able to manage the Web for themselves."
