Me in particular. And the people who forced Stumble Upon and Digg on me are to blame. I wonder how many work hours around the globe have been lost because of these sites?
Only kidding, I love them both and think they often counteract the media's influence on popular culture, a prime topic of conversation at present on the MA New Literacies.
Stumble Upon and Digg are part of a global popularity contest, but they also allow content that has been parodied, developed or altered, along with works without the backing of huge organisations to be displayed and promoted in the online community: a free, open method that hasn't really existed before now.
