I have no idea how good results you get from the skeptic.stackexchange; whether people there track the citations to their original sources, and whether all questions get answered. If that works okay, then I guess the book can only point you towards some questions you wouldn’t ask otherwise.
As I said above, my general heuristic is to post questions that are clear enough that one can think about probabilities to skeptic.stackexchange.
How would reading that book improve on that heuristic?
