Not by everyone, though. In the Chronicle of Higher Education this month, Geoffrey K. Pullum of the University of Edinburgh unloads with both barrels on "grammatical incompetents" Strunk and White for what he alleges are the book's numerous failures to correctly state the rules of grammar. He goes further to claim that Elements itself contains many examples of the authors blatantly violating many of their own rules. Coming in for particular criticism is the book's treatment of the passive voice, which according to Pullum, Strunk and White neither understood nor properly articulated rules for.
It all may seem arcane and boring to some, but anyone who's read an open comment thread on, well, any blog ever is aware that the Internet has a healthy population of grammar police, who will no doubt enjoy the debate. As will lawyers. Lawyers love grammar because grammar is just like law: technical, complex, full of exceptions, and always susceptible to interpretation. Let the arguments begin.
