The fun of serialization

I started a new story by writing out three pages of characterization and plot, then I wrote the first seven pages or so, and gave them to my wife. I plan on finishing the second section of about eight or nine pages today, and get the last part finished by the end of the week. The joy of not having the whole story for her to read is immense. It helps that I've made a bit of a cliff hanger.
I think this helps with pacing of a story as well. It's a wierd way to get a draft out, but if I've learned anything by all this writing is that no two stories are the same, and no two stories get written the same way.
