Have there been any good epistemological studies on the impact of instant messaging and social media? I keep thinking of the book “Amusing Ourselves to Death” and wondering what the authors would have thought of smart phones and micro-burst communication tools like SMS, Twitter, and FB. Clearly it emphasizes the importance of the Sound Bite over fully exploring and developing ideas but I’m hopeful that the medium of podcasting, especially long-form interview podcasts like the Joe Rogan Show, could start to swing things back the other way.
