Internet use study

Fully 85% of American adults use the internet or cell phones - and most
use both. Many also have broadband connections, digital cameras and
video game systems. Yet the proportion of adults who exploit the
connectivity, the capacity for self expression, and the interactivity of
modern information technology is a modest 8%. Half of adults have a more distant or non-existent relationship to modern information technology. Some of this diffidence is driven by people's concerns about information overload; some is related to people's sense that their gadgets have more capacity than users can master; some is connected to people's sense that things like blogging and creating home-brew videos for YouTube is not for them; and some is
rooted in people's inability to afford or their unwillingness to buy the gear that would bring them into the digital age. The typology categorizes Americans based on the amount of ICTs they possess, how they use them, and their attitudes about the role of ICTs are in their lives.
Ten separate groups emerge in the typology.
