It’s never been so easy to pretend to know so much without actually knowing anything. We pick topical, relevant bits from Facebook, Twitter or emailed news alerts, and then regurgitate them. […] 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.
