As digital technologies rapidly evolve, updating and enhancing models of digital literacy pedagogy in technical and professional communication (TPC) becomes more urgent. In this article, we use "digital life" to conceptualize the ever-changing ways of knowing and being in postinternet society. Using collaborative autoethnography, we investigate features of threshold concepts in TPC pedagogy that may support models of digital literacy that are resistant to tools-based definitions, foster student agency, and facilitate accessibility, equity, and justice.

This article is the introduction to the Communication Design Quarterly special issue on digital life. It explains the exigency for this issue and details how digital literacies in technical and professional communication are complicated by emerging technologies. It also demonstrates the potential for moving toward a model of digital life as a flexible way of foregrounding and talking about the work we are all already doing to understand and improve our post-human lives.

This article examines how nonprofessionals in early modern England used tactical technical communication and rhetorical strategies to build medical knowledge and healthcare expertise. Using a feminist ethos and tactical technical communication lens, this article details a content analysis study of 4,045 handwritten medical recipes from England dated between 1540 and 1860. Findings from the study extend tactical technical communication by examining non-digital/non-internet spaces and how extra-institutional nonprofessionals build ethos and expertise.

Teaching writing involves helping students develop as critical communicators who use writing to question often-unseen systems of power enabled by infrastructures, including digital spaces and technologies. This article uses Walton, Moore, and Jones' (2019) 3Ps Framework---positionality, privilege, and power---to explore how, through assignments we developed incorporating the Fabric of Digital Life digital archive, instructors can make visible to students the invisible layers of infrastructure. Using the 3Ps framework, we illustrate how our pedagogical approach encourages students to use writing to interrogate digital infrastructure and the ways it is entangled with positionality, privilege, and power.
