Exhaust the Subject when Writing Content

"When it comes to content, take the time write the best article you can. Don't write a bunch of rehashed garbage ... Write something fresh and recent with new sources. Also, don't make the article short just because you don't like to write. Write until you've exhausted the subject. This will help you avoid duplicate content penalities, increase the stickyness to your site, and put out more 3,4,5, etc. keyword combinations that you can pick up traffic on." Freedom
