I guess the reason it never quite made sense to me is because I don't believe it's significant. Each writer has their own methods but most of them aren't that unique and while they make a difference for the writer that chooses them, they probably wouldn't help writing as a whole if we all adapted the same methods. I mean unless you're writing with a bag of chicken bones hanging from your neck, your process probably isn't that special. Though if you are writing with a bag of chicken bones around your neck, feel free to declare yourself a proud and out Chicken Boner. I won't judge.
However, I do judge people that announce they are a Pantser or a Plotter in a way that implies we're receiving any significant information from that label at all. Guess what everyone! I tend to favor my left when I sleep at night. I'm a Left Sider.
The funniest part is most people fall somewhere in the middle. They plan a little, they wing it a little. So it's not even a true dichotomy. As writers we don't really need to draw lines over silly stuff like our process. Don't we have enough knock down drag outs over adverbs and passive voice?
