Here is another thoughtful article, this time from The Chronicle of Higher Education, about the need to theorize the role of software in digital media, especially the way users interact with digital materials (the article is linked below). Although not the major point of the article, the author Lev Manovich makes an interesting observation about digital humanities:
Over the past few years, a growing number of scholars in the digital humanities have started to use computational tools to analyze large sets of static digitized cultural artifacts, such as 19th-century novels or the letters of Enlightenment thinkers. They follow traditional humanities approaches—looking at the cultural objects (rather than peoples’ interaction with these objects). What has changed is the scale, not the method.
Instead, Manovich argues that “peoples’ interaction with these objects” — not documents, but performances–is the data of the future, and software not only makes new sorts of interactions possible, it is also the means for tracking and analyzing those interactions.
