According to Matt Taibbe, nothing at all:
So over the weekend I read All In, Paula Broadwell's slobberific biography of General David Petraeus.
…..
You can pretty much guess the rest of the plot from there. Every environment Petraeus enters is instantly bettered by his majestic personage. We see him passing through destroyed hamlets in Afghanistan, the weight of the world on his rugged shoulders, scratching his figurative chin as he worries which strategies to choose "so that villagers could once again live in peace and prosperity."
…..
The book is so one-sided that it is almost supernaturally dull, and I was forgetting about it just minutes after I put it down.
Then it hit me – it was an interesting book, after all! Because if you read All In carefully, the book's tone will remind you of pretty much any other authorized bio of any major figure in business or politics (particularly in business), and it will most particularly remind you of almost any Time or Newsweek famous-statesperson profile.
Which means: it's impossible to tell the difference between the tone of a reporter who we now know was literally sucking the dick of her subject and the tone of just about any other modern American reporter who is given access to a powerful person for a biography or feature-length profile.
I wish I knew who the proprietor of Media Whores Online was, because we need him/her (JennyQ aka Jennifer Kelly) back.
Seriously the times demand it.
You cannot tell the difference between a Thomas Ricks or a Paula Broadwell profile of David "Moar Dronz" Petraeus, but only one of them has literally fucked the now former CIA director.
