I definitely agree with that. Most words in a book are just fluff. It would be amazing if someone wrote a book where 100% of the book was information, but the only problem I can see with that is that there wouldn't be complete sentences. The only attempt I've seen that's similar to that is Marc Allen's
The Type Z Guide to Success With Ease. It's that ebook that Steve talks about. What Marc Does is he'll write his book, but he puts these bold, blue centered words in the middle of the page, outside of the story and the bookand it gives you the actual feel of the book, and if you're "lazy or type A" as he says, you can just read that and get the whole idea. I really like that way of writing. He doesn't mess around, he gets right to the point. I kind of understand photoreading, but i really don't know how to activate it, as I haven't bought it yet, but I often read very fast if I'm reading with a purpose. But I'll have to check into it eventually...
