 Finally, there are pressing practical concerns about whether and how philosophers can actually have an impact on the ethical profile of emerging technologies such as SNS. If philosophers direct their ethical analyses only to other philosophers, then such analyses may function simply as ethical postmortems of human-technology relations, with no opportunity to actually pre-empt, reform or redirect unethical technological practices. But to whom else can, or should, these ethical concerns be directed: SNS users? Regulatory bodies and political institutions? SNS software developers? How can the theoretical content and practical import of these analyses be made accessible to these varied audiences? What motivating force are they likely to have?
