Is your target audience absolute beginners to programming or experienced programmers who want to learn Rails?
One thing I Have never seen is a "why" you should learn Rails and what you can do with it. What kind of web apps can I build? What can I do with it? Why would I want to?
Personally, I don't go for the informal tone, but it wasn't over the top and many books tend to go that way so no problem.
I like that it seems you won't be preaching about side technologies like git or tdd. It is an added difficulty when people add extra complications to a book, especially an intro level book. My personal opinion, don't go preachy on formatting or style either, just use well written examples for people to learn from and they will pick up your style.
