PostSecret (www.postsecret.com) is a transitional space where the in-betweenness of public and private exists. Within this space, peer public pedagogy occurs through critical participatory democratic interactions of community participants. Integrating PostSecret into the art education curriculum can offer the potential for generative knowledge formed through participant collaboration in this informal learning site. In this article, the author discusses PostSecret's affordance for "peer public pedagogy". Next, she contextualizes postcards and analyzes them as "currere". She then argues that PostSecret fosters informal art education and online feminist pedagogy by exploring her integration of PostSecret in the graduate art education curriculum. She then examines Aoki's (2003) "curriculum-as-lived" theory, its application to PostSecret, and PostSecret's empowerment potentials. She concludes by recommending that art educators consider PostSecret as an informal approach to art education. (Contains 7 figures and 1 note.)
