I've never liked the "idiot's guide" or "for dummies" thing, either. But, FWIW, keep in mind that this is a slide deck taken out of context. In context, it was probably being presented to an audience where a certain level of background knowledge could be more safely assumed. And, in context, it was probably being presented by a real live human. That means that there was a whole lot of more detailed explanation that is not available if you're just reading the deck. And also a human face to make any tongue-in-cheek bits (I'm guessing the title was meant to be at least a little bit irreverent) more apparent.
