To write an appealing and good article requires a clear, yet good content as well as excellent techniques. As a composer, I know one trick to writing anything good is by minimizing the barrier to entry so that the audience are easily drawn in. Another necessity is that it provides substance-- you don't want to provide an article with no meaning and says absolutely nothing-- a content should not be written just for the sake of it-- it needs meaning as well as understanding, it should also tell a story because lets be honest, everybody loves a great story. These are a few tactics I implement in my own blog and will more than likely use in your article to give it flavor. The only question now is when do you need it and what's the article covering?
