DIY advertising

So, in my principles of marketing class today, the professor was explaining different types of advertising, among them, Do It Yourself advertising. As an example, he pointed at my can of cherry coke and said "Do It Yourself marketing would be like, Chris goes home and writes in his blog: Cherry Coke tastes great and doesn't make me fat!". Or something to that effect. So that's exactly what I intend to do. Cherry Coke tastes great and it doesn't make me fat.
