Аннотация:This study explores community life on a black social network site, BlackPlanet, to see whether and how participants engage in public discussions; if these discussions center on issues considered to be critical to the black community; and if so, the extent to which participants' online networks are used to foster some level of civic engagement. Participation analysis, content analysis, and a thematic analysis were used to analyze public discussions on the site's community forums. The findings show that participants are deeply committed to ongoing discussions about black community issues. However, none of these discussions moved beyond a discursive level of civic engagement, suggesting that the potential for mobilization through social networking online has not yet been realized, despite the traditional orientation to community service among blacks in America.
