On Track With "Do By Learning - The Book"?

I am thinking about self publishing a book called "Do By Learning" to start experimenting with social media marketing strategies and then adjust dobylearning.com so that it is built around the ideas in the book.

So far I have an outline and some text that shows where I am currently planning to take the idea:

What I need to know as early as possible is

1. if these ideas are too far removed from your way of thinking about things
2. if what I write raises more questions than it addresses
3. if the writing style is horrible
4. if there is something right with it that I should keep
   ?

Any other remarks?
Thanks!

Edit: I created a version that takes the feedback I got into account:
