No, I wouldn't try another book from Jon Najarian. This was a waste of time and money.
Jon likes to let you know that he is a remarkable guy. He starts with a narrative about his pro-football days with the Chicago Bears. I was looking for a book about LEAPS, not about Jon Najarian. He barely touched on LEAPS, but he did have a lot of anecdotes about his trading days.
I'm stopping this review short. Already wasted too much time on this book. Good luck if you choose to move forward with it.
David Weinberger's lecture is quite interesting, and speaks at a level easy for most people to follow. He contrasts past and present knowledge organization schemes, and explains how this is important for the Internet.
