I moderate and post regularly to The Yolk: A Blog Theory. It hosts reports, rants, images, theories and so on by several graduate students at University of Alberta and elsewhere. Discussion varies based on affect, but usually involves the interactions between politics, community, and aesthetics conceived broadly.
 
We invite your comments on the blog or guest posts (send your requests to yolkblog[at]gmail.com)
 
I am also actively affiliated with the Space and Culture blog and the Space and Culture Research Group.
