I like the New Yorker magazine's take on grammar as I observe it by reading their articles.
I don't always comply in my own writing.
That is because:
That is such nonsense, Osso, but at least you can feel warm in that it is really old nonsense. You follow those "rules" in your own writing because they are the rules that everyone follows. We follow rules that are real, natural rules of English.
You don't, of course, follow every style that a published magazine would because your writing isn't meant for publishing.
People, like Eva and actually Joe, are only aware of these silly rules when someone points them out. Can you imagine that for all the times that Joe has read similar constructions at A2K, this is the first time he's ever mentioned this "rule".
Language and grammar is extremely complicated stuff. You realize this because you know that you can't explain much of anything about how language works and yet you use language, more or less, in a perfect fashion.
The New Yorker's take on grammar is probably good on the odd occasion. But most/many of these style grammars are filled with old, arrant nonsense.
