Rivenbark's tone was meant to be sardonic and honest-to-a-fault, but often comes across as bitter and overly defensive. She is funny, there is no doubt that her voice has a strong, Southern twang that leaps out of the words, but she focuses so much on what she is not (A Supermom, hip, into documentaries, young) that the negativity becomes very tiring.
There is a definite niche for these kinds of writings, and a need for it but Rivenbark's writing has become dated in just five years since publication. There are two references to Michael Jackson that had probably been funny while his trials were ongoing, but now that he has passed, just seem mean-spirited. There are also mentions of Hilary Duff, Days of Our Lives, and Paris Hilton, all three of which have not been part of the cultural zeitgeist for some time. And the most troubling part, much of Rivenbark's writing sounds lifted from mom blogs, which either speaks highly of Rivenbark's relatability or poorly of her originality. You pick.
