When I started writing articles, the first rule that I always follow is checking if my article is nice to read. We should be writing for our readers and not for ourselves nor for the money. What is the use of the article if no one enjoyed reading it? What I do is to have 2 people read my article before I make it final. When one of them says it is boring then I have to rewrite until they both say that the article is good. At least that is a gauge for the reading quality of my articles.
