  18. Community standards exist, but are rarely written down, regarding speech patterns and vocabulary, driving attitudes and customs, and the definition of pornography. These standards differ frequently between urban and rural environments in much the same manner as political preferences differ. Thus while the law may (or may not) explicitly specify set limits on certain citizens' activities, the local standards and the local environment may further limit or extend acceptable practices.

    Describe a local (urban or rural) convention within your experience which differs from legal requirements, and then discuss how such local variances have an impact on the establishment of practices and protocols for the use of computers, where few laws have yet been established.

If you were (or are) of some other denomination (or agnostic), would you be offended by this "take-off" on the "Ten Commandments"? Would you be concerned that this was mixing religion and professional behavior in an inappropriate manner? Explain your arguments and suggest alternative strategies for presenting ethical guidelines.
