I'm flattered by you question, But I'm far from an expert. I enjoy reading more than writing and have made some very nice friends in my short time here. My opinion would be to see what is hot in the news. I personally think when you write about something you totally believe in, That is what makes it great as a lot of emotion and excitement goes into it. I do not do this for Money, so I do not know how that part of it works. If you need help some people on here are actual writers who make money and most are very helpful.
