Ask HN: Does explaining your program's complete design reduce sales?

I'm working on my very first Android application; and, I've been considering talking through the different parts of my design; and how and where my code is growing organically to support the different ideas that I have.

Since I'd basically be explaining every feature and design decision I make from here on out, this leads me to a question. Would I lose sales from my application? I'm very interested in selling it.

It's an active wallpaper that plays the Game of Life. I know the market already has one, but I was going to be adding more features to it that would make it more interesting and perhaps a good wallpaper.
