premise: 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 and true is true and true is true and true is true and true is true and true is true .
hypothesis: The books are superior to the columns because of the vast increase in writer-reader interaction present .
