Together, computerized writing environments (e.g., physical spaces, hardware, software, and networks) and the humans who use and support such technologies comprise complex ecologies of interaction. As with any ecology, a human-computer techno-ecological system needs to be planned, fostered, designed, sustained, and assessed to create a vibrant culture of support at the individual, programmatic, institutional, and even national and international level. Local and larger infrastructures of composing are critical to digital writing practices and processes. In academia, specifically, all writing is increasingly computer-mediated; all writing is digital.
