Seth Godin hardly needs an introduction if you’ve been paying attention to online marketing for the past decade, so I won’t bother. One of the books a colleague at work keeps in her “lending library” is Purple Cow, his penultimate book. Subtitled “Transform your business by being remarkable,” Purple Cow is in style a magazine article stretched into a book. (Here’s the free magazine excerpt.) A few basic points, repeated and illuminated, fill less than 150 small pages. Since I don’t need an O’Brian novel or a Clancy brick every time I start reading — who does? — the length is not a negative. Godin gets his point across and then finishes up with a bunch of Brainstorms, paragraph-length discussion starters. Godin is his own Purple Cow, which is actually pretty remarkable. Side note: has anyone since Telly Savalas made being bald a signature item like Godin?
