From Henry Jenkins
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.”
“Here we are” is not only more important, it is also closer to the truth, since it hides whatever implicit subjectivity is present in “Here I am”.
But where? Twitter is nonspatial; the internet is everywhere and nowhere. Twitter is nontemporal, or at least asynchronous; ‘we’ do not share time.
Twitter is location without coordinates. “Being here” is the final reversal of the implicit subject-object distinction in dasein itself, setting context without any reference to the other.
we are no longer dasein.
