Although you mention in response to Mr. Austen's comment ("Sideband Suspicion," September 2011) that creative thinking should not be abandoned, it seems to me our editors' value lies in discerning creative correctness and creative falsehoods. I can see where this may be a fine line in some instances, but tech articles should be vetted for correctness. I would hope your tech articles would not be misleading as it appears Hal Walker's work is.
