Abstract:

People in the computer industry frequently toss around the term 'computer literacy.' They talk about how some people have it and some don't; about how those who have it will succeed in the information age and those who lack it will fall between the social and economic cracks of the new age. But computer literacy is nothing more than a euphemism for making the computer user stretch to reach an information age appliance rather than having the appliance stretch to meet the user.
