Well to be honest I wasn't really reading it for advice. I'd read Motley Crue's The Dirt a year or so prior, was curious what else Strauss had worked on and thought a book where he becomes a pickup artist would make for a more interesting read than an autobiography by Jenna Jameson.
I guess if you look at it logically most of the advice they give boils down to stuff that really should be common sense but admittedly isn't to a lot of people - i.e. dress properly, be confident and don't act needy or desperate. They just wrap it up in unnecessarily dorky lingo that makes it sound like they're playing D&D. But really, if you read the book the characters end up pretty broken, completely lose their individuality and become so obsessed with PUA that by the end of it they're spending far more time swapping routines and squabbling amongst themselves than they actually do picking up women.
