Amazon will open BookScan to authors (just in case Amazon rank doesn't mess with your head enough)

I know information is power, but I have mixed feelings about Amazon offering authors access to Nielsen BookScan via Author Central because A) BookScan is Satan and B) BookScan results without ebook numbers are rapidly becoming even more skewed.

But I guess it's good to have. Just in case the Amazon sales rank doesn't do enough of a number on us...
