In an age of unending information, basing one’s work on a past of referentials can seem foolhardy (in America). One, educations are getting worse. Two, even nominally good educations will tend to miss a lot. We are no longer in medieval universities. There is little use (or should this be in quote marks?)” in including subtle references to the minor plays of Shakespeare, or to Sun Ra, or to Lorrine Niedecker. Unless your reader happens to be a specialist, even in a general sense.
And yet sometimes with this lack of utility…there can be an excess of pleasure. But it can also create despair in the writer. If the references are unheeded, then what is the use? The audience–already small–winnows.
I suppose this is also how the Decemberists got popular. Their relying on this.
