I read danah’s draft essay too and I think what we are seeing is a shake out of all these services. It is impossible to be ‘blind to class lines’ and ‘all-access’ in practice - inevitably things get complicated by cultural capital (cf Pierre Bourdieu) and taste as a marker of class. I think it is better to be aware of the different audiences that services attract and different behaviours - a quick look at the stats in Quantcast of various services reveals quite different demographics across many sites. I’ve been using the example of Photobucket vs Flickr but you could also compare institutions.
