I have been reading from people asking how long does it take to write an article for the internet, and they then go no to claim it takes long for them. They open a new page on a site like Wizzley, which is where this article was published. Then, look up bits and pieces of information for the topic they intend to write about, adding small bits over hours, days, or even weeks.
First, I do not pick a topic I cannot write about without looking up the main portion of the material. Some details may be looked up, such as when I write about a coin I might look up its mintage, but I would probably already have some knowledge of my topic before beginning to write. Writing on unfamiliar topics causes one to misinterpret what is there, especially if it is a technical topic. I have read many errors articles written for Hubpages on scientific topics, the material just does not match my physics training. So, first write on something you know, or can easily come to know.
