Mark Bernstein does a great job of explaining how some of the "old guard" in literary criticism just aren't keeping up. This is nothing new, either - I recall the old guard in the 80's criticizing the word processor as an abomination, saying that the typewriter forced the writer to carefully consider his words. I'm sure that the great grandfathers of those folks deplored the typewriter, as it made the creation of words too easy (compared to longhand). Going back hundreds of yeas, I know that Gutenberg horrified as many people as he enthralled.
The more things change...
