What is this "post-" in postracial, postfeminist... (fill in the blank)?

The events of the 2008 election continue to spark prognostications that we live in a world that is postracial/feminist, and so on. At the 2009 NCA (National Communication Association) convention, a panel of communication scholars discussed how to approach questions of identity and communication over the next 5 years. Participants suggested ways to be critical of assertions of "post" and elaborated ways to encounter new dimensions of identification in an era of immense sociopolitical challenges. This forum revisits the exchanged dialogues among the participants at the roundtable and further explores the meaning of post- in post-America.
