I certainly enjoy reading it. I've always found his articles insightful and well-reasoned, and if I happen to learn a new word or two in the process then all the better.

Generally when I read something and judge it to be pretentious, it's because the author is using words that are out of his/her depth, in an attempt to impress the reader. When Jerry writes I get the impression he's choosing his words carefully and with equal intent to entertain and to inform.
