My grammar checker has no problem with this silly sentence; though any thinking reader would, and even assigns it a 12th grade reading level. Conversely, when I test sentences from one of our most lyrical works on science and nature, Loren Eiseley’s The Immense Journey  the grammar checker frequently wags its finger unhappily at the author, befuddled by his comma use, syntax, and sentence length. To put it plainly then, “Grammar checkers is stupid”—another sentence my checker accepts readily.

In other words, they do not think. Since we do, we must and can learn to outperform them.

With these concerns in mind, I certainly do use and recommend grammar checkers to thinking writers, following these guidelines:
