You/one may/can/might break "rules" willy nilly/willynilly/willy-nilly in every day/every-day/everyday writing or speech. It's perfectly alright/all right to do so, although/though/albeit there are several examples of inelegance in this lot that I wouldn't like to see in a novel, a learned journal or one of my regular posts here. Deliberately breaking rules, such as in a light-hearted series' of post's to do with the apostrophe and it's misuse, is perfectly literate. What isn't literate is breaking rules unknowingly, excusable in most cases but inexcusable when the writer is indulging in high-flown tones or when he's criticising someone else's alleged breaches. That's what Nigel did (though I cheerfully admit that it was probably just a bit of rubbishy proofreading), and that's a practice from which we would be well advised to swiftly move on. God, how I love those split infinitives. A great example of a rule that was never a rule in the first place. As with incomplete sentences. And as with starting sentences with conjunctions. Even those damned incomplete ones. There are times when nitpicking over rules is simply not apropos.
