This is a rough draft to me. I feel like we're reading a first or second edit, and it needs a lot of clean up and some rewriting stuff. It's explaining concepts for the most part, but he doesn't illustrate those concepts very well. And yet, there's of good ideas in here, just not packaged like this. That said, how do you rate this? Oh, gosh, pardon me. Wants to just say point five, just to be a snot. But that's, i don't think it's that bad. You know, it's got a lot of work that needs done.
