Tocqueville in Cyberspace: Using the Internet for Citizen Associations

Political theorists like Alexis de Tocqueville have long recognized the importance of citizen associations for the practice of democracy. Through participation in associations, citizens both receive an education in public affairs and create centers of political power independent of the state. Essential to participation in an association is participation in a forum, a communication space that allows for many-to-many communication in which citizens can "treat of public affairs in public" (Tocqueville, 1945, p. 109). Participation in forums suffers from numerous barriers, however, such as the need to meet in one common place, the need to meet at one common time, and the potentially high costs of participation. Online forums on the Internet avoid many of these barriers, and thus they hold the promise of facilitating the formation and operation of citizen associations. This was confirmed in 1995 by the experiences of a Boston-based citizen association, the Telecommunication Policy Roundtable-Northeast (TPR-NE). TPR-NE's uses of the Internet suggest that online forums may allow associations to be more responsive, more robust, and able to unite more members.

Our Own Devices: Heterotopic Communication, Discourse, and Culture in the Information Society 1

The main premise of this article is that in information societies generally, and in virtual social contexts particularly, a distinctive style of interaction to facilitate the communication of difference, heterotopic communication , has emerged. It rests on two cultural foundations: an ideological belief in the positive, socially integrating power of communication, and a prevailing ethic of instrumental rationality, subjective individualism, and strategically practiced self-interest. The former is demonstrated by the use of simulation and spectacle as sources of information; exhibitionism/voyeurism as a communicative style; and the awareness of surveillance. The latter is seen in the competitive use of knowledge as a commodity; a surface globalism masking deep parochialism; lateral as well as vertical information inequity; and the use of public versus private as strategies for engagement rather than as spaces. Those who engage in heterotopic communication resort to their 'own devices' both in the sense of personal agendas, strategies, interests, and interpretations, and in the form of the telecommunication tools that help realize them. These personal and technological devices allow individuals with the right educational and technical resources to avoid exposure to disagreement, difference, or other information that does not serve their direct purposes or reflect their particular views of the world; yet they also help convey the appearance of openness, availability, and cooperation. This style of interaction is used strategically in combination with information and communication technologies to gain social or economic advantages, but it may encourage social separatism and parochialism, inhibit the negotiation of disputes, and emphasize competing interests.
