… From the start, I’ve questioned whether Twitter was the right medium for me to do my work. I’ve always said that as a writer, I am a marathon runner and not a sprinter. I am scarcely blogging here by traditional standards given the average length of my posts. Yet I believe this blog has experimented with how academics might better interface with a broader public and how we can expand who has access to ideas that surface through our teaching and research.

Someone recently asked me, “If McCluhan is right and the medium is the message, what is the message of Twitter?” My response: “Here It Is and Here I Am.”

Here It Is
Let’s break that down:”Here it is” represents Twitter as a means of sharing links and pointers to other places on the web…

Here I Am
… Here we come closest to McLuhan’s core idea — “Here it is” is a function of Twitter; “Here I Am” may be its core “message” in so far as McLuhan saw the message as something that might not be articulated on any kind of conscious level but emerges from the ways that the medium impacts our experience of time and space.

"Here it is" became "Here I am" and more importantly "Here we are."
