Seriously?
Your not updating your story because you want more comments? Writing should be for fun and not just to gain comments and praise. You should want to continue this story for the one person that continually comments.
I've been reading this story from the beginning as you update it but I cant comment from my phone or my laptop because I read it during my breaks from work.
Having an attitude like yours isn't gonna make people want to read this story and feel completely obligated to comment on every chapter.
You write for you, you write to be creative and to publish your story for the world to read and enjoy.
Just because people don't comment doesn't mean we don't like it or don't read, its just sometimes we have more important things than leaving a comment.
