Thanks for your input Chris_Jr and Digifeminist--you make some important observations. Chris do you have a twitter handle so I can publicize your comments?
These comments and the article itself made me go back and question how well postcolonial studies itself deals with race, especially with the whole idea of whiteness as privilege. This made me start reading a book I have assigned for my fall class on colonial/postcolonial research methods: Alfred J. Lopez: Postcolonial Whiteness: A Critical Reader on Race and Empire. This anthology has proven very helpful to me as I realize how the assumption of whiteness lingers on in both postcolonial states and, for the purposes of this thread of conversation, in emerging areas of new scholarship like humanities computing which gave rise to DH. So, my question is not why is DH so white, but how can DH and poco scholars, fans, novices, etc. destabilize the assumption of white privilege as the default mode for knowledge production.
