First decent new sentence I’ve added to my PhD draft for a couple of weeks:

Flickr can be viewed as the site of a vernacular ‘relational aesthetics’ (Bourriaud, 2002), where the object of the aesthetic is no longer the image itself, but the ‘modes of social connection’ (McQuire, 2006, pp. 263) that are both made possible by and flow through the image.
