Collaborative writing helps you apply creative writing techniques quickly and with ease simply because two or more people are working together to instill an idea. For instance, I learned how to write jokes with the help of my ex-fiance. He used to edit all my writings and actively participate through comments and suggestions. By the way, I am still learning how to write good jokes simply because I find it a bit difficult to do so. Writing is an elaborative process and there are so many genres that slow exploration and review is the only way to create long-lasting impact.
