That same post I'm ignoring back on goodreads also pointed me to this great link: 


"Good reviews, as expected, increased sales across the board, with gains from 32% to 52%. For books by established authors, negative reviews caused a drop of about 15%, on average—also not surprising. But for books by relatively unknown authors, bad reviews caused sales to rise, by an average of 45%. This held even when the criticism was extreme: After one particularly scathing review, for instance (“the characters do not have personalities so much as particular niches in the stratosphere”), sales more than quadrupled.


The reason? Our analysis showed that by making consumers aware of a book they would otherwise not know about, even the harshest review can be a boon."


(Personally I suspect back on goodreads that by their confrontational actions some authors actually attempt to get 1-star ratings because so many features and discoverability possibilities on goodreads sort by descending number of ratings.  The key phrase being number; goodreads doesn't distinguish between 1-star or 5-star ratings, just the quantity in some features, including exploring by genre.)
