Instapundit notes that Sylvia Ann Hewlett's book isn't selling.
I think he's dead on when he says:
Yeah, there's a whiff of 1987 about the whole enterprise, it's true.
From what I understand there are two parts two Hewitt's book - the well-researched part about declining fertility, and the hysterical rant about the misery of being childless. And, yes, we've heard that part before. I'm sure we'll hear it again. I'm glad it isn't selling so well this time. It's also nice when the media promotion machine fails.
