Compiling this commentary seemed a unique assignment. True, students are often expected to contrast or critique various ideas, arguments, or literary forms in published works. However, for this commentary, we were asked to relate or otherwise make sense, not of texts seemingly congealed in print, but of exchanges created through an ostensibly more tentative, transitory medium, e-mail. Texts produced for publication are generally expected to be developed, edited, and manicured with great care, but an e-mail may be dashed off with little time devoted to spelling or punctuation, let alone to ideas. Yet, despite such perceptions about print vs. electronic media, the ideas in the e-mails that served as sources for this commentary, e-mails from Gee, Kalman, Mahiri, and Sperling, were both thoughtful and thought provoking. At the same time, the process of reading early versions of the authors' contributions to this volume, posing questions to the authors, and then receiving feedback from them via e-mail highlighted for me both the hybrid and dialogic natures (Bakhtin, 1981), not only of e-mail, but also of the writing process itself (see also Brettschneider, this volume).
