Both dana boyd's original post and Benjamin Doxtdator's response are really strong posts and I recommend you take the time to read both carefully. I cited a previous post from boyd recently making some of the same points. Essentially, boyd is saying that we need to 'innoculate' people from deception in media, while Doxdator is saying that this fails to address the power dynamic in society. The disagreement is most evident in the different ways we treat experts and authority. As Rene Hobbs says, "Media literacy educators, with their focus on evidence and reasoned argument, value expertise even as we point out that expertise is itself a social construction."
