Birkerts cites Cynthis Ozick:
What is needed," Ozick writes, "is a broad infrastructure, through a critical mass of critics, of the kind of criticism that can define, or prompt, or inspire, or at least intuit, what is happening in a culture in a given time frame. . . . In this there is something almost ceremonial, or ceremoniously slow: unhurried thinking, the ripened long (or sidewise) view, the gradualism of nuance."
To which I would respond: Nothing is stopping anybody from being unhurried in their thinking, letting their views ripen, so that no nuance is released before its time - and posting the results online when they feel ready to. Just because the Web allows one to do things quickly doesn't mean that everything done there must be done quickly. As a matter of fact, it is those of us in print media who face the tighter deadlines. As I have said before, newspapers' cutting back on book coverage will do more harm to newspapers than it will to criticism or reviewing.
