Astounding
This guy's "marketing" ideas are astoundingly poor. Where did he go to business school? "Stupid U." probably.
Just one example of his inappropriate/embarrassingly-uninformed "ideas" is to flavor a type of yogurt as "poo." Yes, it is exactly what you are thinking of - feces. Predictably, the idea does not go over well once customers taste the strangely-flavored yogurt. Admittedly, his strategy was to cause controversy in order to attract the curious and not necessarily to create a yogurt that had a pleasant flavor; in my opinion, though, in order to retain customers, the product must be at least acceptable. In this case, it was not.
Several of his other ideas are equally amateurish, but at least he uses novel approaches. Overall, though, he should do more research on targeting the correct demographic and looking at the dynamic of marketing and retention.
