Apologies if I'm not sending this correctly. I get the digest, and so I'm not sure how to reply such that it responds to the thread. In any event. My professor (Munmun De Choudhury) and one of her PhD students (Stevie Chancellor) do a fair amount of work in this area. Three of the papers below use Instagram, another Tumblr, and I can't recall the fifth at this moment. You can find the links here: http://www.munmund.net/publications.html Unfortunately, Stevie's publication links are down but here's her info: http://toppling-dominoes.com/ 1.
