"node takes a leap from that that says"
"and use it to make a easy way"
"the rigth way of doing"
"what many people belive is the right direction"
All in the section "Why the sudden and exponential popularity?" (which is not even a very long section).
However, that aside, this looks good. The style is pacey and informed, the content looks useful and sufficiently technical without being a physics paper, I might even stump up some cash after reading the free pages.
No problem, I used to be a technical author ;) so kind of hard to lose the habit. I really like the book. I hope you don't think I'm being too critical, and I hope you make some good money from it.
Still, he is smart for moving fast, and it looks like there is good value here.
