This thread is many years old. Mark's book, which was excellent upon its release, remains excellent, and those who don't own a copy should buy one. His book has and will continue to stand the test of time.
What has changed since this thread is Mark Wilson himself, who has further distinguished himself as one of pool's greatest figures. He is not just a legendary instructor, a great author and a superior commentator, but he is now a three time Mosconi Cup coach, the architect of a college scholarship program for billiards in Missouri, and one of American pool's greatest ambassadors. Mark has aged like a fine wine.
