I agreed to the 6C method of Feng.
Article should be simple so that everyone can understand it.
It should be so clear and complete so that everyone can really know what we mean in there.
And it should be colorful and consistent so that they an get the important part of the whole article and love the presentation.

I always say that expression is everything, if you can express your feelings to the reader, you will get their expression too.
If it can express the whole thing with in couple of line then it is okay, and if it does in a long way but express all,then it is also okay. Length is not the main thing but following those 6C is much more important.
