This guy’s got something against bovine
Dean Wesley Smith has got something against the publishing world, and so he’s writing a book about it, Killing the Sacred Cows of Publishing.
Smith, known primarily for his book adaptations of television shows, movies, etc., has identified over twenty-five of what he says are writing and publishing myths, and has been ever so kind as to set writers straight with a series of book chapters on his website (which, if you enjoy, you are invited to donate toward). But what Smith seems to have forgotten is that the entire writing/editing/publishing/agenting/reading world is subjective, and that his opinion does not make something fact.
To be sure, there are some gems up there, and some pretty unarguable statements: writing slowly does not mean writing well, and writing quickly does not mean writing poorly; all writers are different, have different habits and strengths and weaknesses; writing requires practice. Most (though not all) of what I agreed with had to do with writing advice—which is unsurprising given that Smith has published over ninety books (even if he did have a pre-established base for many of them, such as character and world).
What he really seems to hate, though, are agents*. He is quick to mention the 17-year relationship with his own agent and that he is friends with a few agents, but it is all but impossible to miss his disdain for their usefulness, unless they are top tier, and especially for new writers.
