Because I don't consider myself to be qualified to be able to help in any capacity other than editing. Quoting from this post of mine, "To put things into context, although I've owned Apple computers exclusively since 1988, I'm not a power user at all. Everything I've learned about using my computer was not due to interest but out of necessity. To me, my computer is just a tool, and I've only learned what I've had to in order to do what I needed to do."
