More immediate

I’ve been thinking more about the immediacy effect after blogging about it here. In that post I was thinking about the illusion of the synchronous evoked by microblogging (Twitter) and that sense of the nearly now. But I’m now realizing that immediacy is a far more subtle concept than I first thought. For something to be immediate it has to be instantly available at this point in time and in this particular place. On demand and just in time are fashionable ways of saying the same thing. But looking at Bolter and Grusin’s book "Remediation" you also get the sense that the immediate is similar to the un-mediated, or at least the tendency towards it - a sort of invisible or immersive media or what you might call the nearly real. Virtual reality, live broadcasts, reality TV, and YouTube all move in this direction in their attempt to produce, or reproduce the authentic.
