Was about to say the same thing:

"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.
