Take the following as truth: True, there is an occasional mention in his column of a point raised by a correspondent, and the Letters section of the Magazine prints a comment from time to time, but an important feature of the books is their inclusion of far more writer-reader interaction than one might suspect from reading the column alone.

Answer: Inconclusive
