I looked at the vote breakdown, since 48% seems an impossible figure for 7 reviews. 29%, 43%, 57% – 2/7, 3/7, 4/7 – yes, but not 48%. It says "we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzes reviews to verify trustworthiness."
Shouldn't we all go bomb the book and give it one stars and write reviews telling everyone not to buy this book? After Kernighan calls it “malpractice”
