I didn't really read this whole thing, but the gist of it is that increasingly people have no problem discussing the cultural events of our day without actually knowing anything about them.

What we all feel now is the constant pressure to know enough, at all times, lest we be revealed as culturally illiterate. So that we can survive an elevator pitch, a business meeting, a visit to the office kitchenette, a cocktail party, so that we can post, tweet, chat, comment, text as if we have seen, read, watched, listened. What matters to us, awash in petabytes of data, is not necessarily having actually consumed this content firsthand but simply knowing that it exists - and having a position on it, being able to engage in the chatter about it. We come perilously close to performing a pastiche of knowledgeability that is really a new model of know-nothingness.
