Debating the Events of September 11th:
Discursive and Interactional Dynamics in Three Online Fora

This study examines the constituencies, patterns of interaction, and ideologies in three online fora created to discuss the events of September 11th, 2001. Drawing on comparative case studies, the research explores the frames and discursive styles used by Brazilian, French, and American participants to articulate their views about this polarizing topic. The research identifies commonalities and differences across the three cases with respect to trends in posters' participation, interaction patterns between forum participants, and the ideological content of the posts themselves. Interpretive examination of posts from the three sites elucidates linkages between modes of discourse, ideological positions, and faction membership. The article addresses the effects of these discursive proclivities by examining how participants in each forum create stable ideological divisions. It illuminates how different interactional strategies may facilitate or inhibit continued dialogue in the face of division.
