For me, Twitter is predominantly a link discovery service — admittedly, that is a simplified view, but it’s helpful for these purposes — so I followed-up on her Twitter comments by asking where she discovers links. “What do you mean?” She couldn’t even understand what I was asking. I rephrased the question: “What links do you read? What sites do they come from? What blogs?”
"I don’t read links. I don’t read blogs. I don’t know. You mean like funny videos on Facebook? Sometimes people post funny links there. But I’m not really interested in anything yet, like you are."
Television was a major blow to reading for decades up until the internet, but now even the internet is starting to destroy literacy. It's very unsettling.
My impression is the exact opposite: I see people reading and debating more than ever thanks to the internet. I think thanks to the internet we are in a golden era of literacy, but we just don't notice it because we're too busy complaining with other highly-literate people on highly debate-focussed websites such at this one about the more obvious non-literary manifestations of popular culture.
