Chances are, when you’re writing a blog post or article, you save your notes in a Google doc or maybe even in Evernote. A book is much more complicated project to organize, due to the volume of material. Whereas you might save an article or two to read before writing a blog post, you might have 50 or 100 bookmarked for book research. A Word or Google doc can become unwieldy and overwhelm you when you realize just how much information there is to keep track of, let alone in an organized manner: articles to read, websites to look at, hashtags to search on Twitter, people to interview.
