I saw a one-word review at Amazon today. So I’m guessing the 20-word minimum has been removed.
You might recall a couple of months ago that Amazon was testing out both ratings and reviews on print books. Those ratings disappeared after a few weeks, so perhaps the compromise was to remove the minimum word count.
The review forms have changed (but there is a tiny ‘here’ link below them that you can click if you prefer the old way).
My guess is that Amazon is trying to encourage more genuine customers to leave reviews. So now there is no ‘imposing’ 20-word minimum.
(In reality, what had been preventing a customer from writing the same word 20 times consecutively?)
We’re short on time now, so give me a one-word summary of the last book you read. 😉
