I found this simple page of Some Dos and Don’ts in writing. Some of the things listed are common sense, but others may not be so well known.
However, one of them I didn’t understand at all and would appreciate some enlightenment. Maybe I’m not fully awake, although I should be it’s almost 1pm, or maybe my brain isn’t working, but the following means nothing to me. It’s complete gibberish.
Case: “There is perhaps no single word so freely resorted to as a trouble-saver,” says Gowers, “and consequently responsible for so much flabby writing.” Often you can do without it. There are many cases of it being unnecessary is better as It is often unnecessary. If it is the case that simply means If. It is not the case means It is not so.
Edit: OK, it’s starting to sink in now. I think I’ve almost got it.
