It’s a sales/marketing book about microtargeting individual people and organizations with creative, wacky campaigns. In that context, it’s a totally fine and useful read for someone with not much exposure to the field - if only to get the stories and general psychology of sales. Will I use any of these techniques? Probably not, at last in the short term. But it was an interesting and very compact volume that helped me get another data point in an unfamiliar field.
