Well, I've tried one or two in my time, but it doesn't seem to do much for me. The time you take to organize it could be better used actually writing. Frankly, a simple spreadsheet tracks characters just fine for a novel (assuming you have quite a few to track) and a few notes in a notebook or on a notepad probably will do to capture scenes, dialogue scraps, and plot points. My biggest problem (other than a fluffy style resistent to change) is plotting and I've yet to find any help in the writing software. It won't cure things that you don't like to do anyway (I bet it's no secret I hate to write narrative...well, the software won't do it for me, alas). So, I think, it might be helpful if you are truly hapless about getting organized, but I wouldn't expect to become a good writer (or even a better writer) as a result of buying a system. But I also hate those time management tools that make you set goals, objectives, and detail out your life in fifteen minute intervals. It may just be my personality rather than the software that is the problem. The one exception might be in the arena of screenwriting which has a specialized formatting that is used. It won't help you with the writing, but it will help you laying out your product so it can look professional when you go to sell it.
