The English language is not blessed (or cursed) with the equivalent of the Académie Francaise, more or less official body in France, the French language. Differences about correct grammar are sometimes hotly argued by the academy, but outside their decisions are taken as law.

If they say that a grammar can spoil good content writing sounds like heresy, it was. If I use the Web for writing tips, too often the first piece of information that is returned is "Be sure you have good grammar." But its an indication of the car before the horse. It's like a carpenter who say hammer to use to the particular type of nail.

It is only valid if the carpenter knows why it's on the nails, and what will follow.There is the second reason why this time to advise, is lost. A person a good idea, grammar is not necessarily another.English grammarians also constantly argue with each other. Of course there is a broad agreement on a number of things. However, if it is not, you can to a large extent, how you want.
