If you like Jason Ricards's summaries, consider
getting him/her some more books to read!

Upon reading the reviews I think I will have to read the actual book. It seems like a really good topic and could be very valuable in my marketing career. Honestly when you think about in marketing all you are doing is trying to get others to follow the herd or create a trend so that you product or service is valuable.
