For the record, I'm now in the midst of stripping the star ratings off the books I've reviewed
on Goodreads. I'm going to try out a review-only, no-star-level method. I feel too much importance is placed on the number of stars rather than the words. If someone writes a respectful review saying, "I liked A, B, and C and thought the flaws were X, Y, and Z," and posts that review under a two-star rating, the author will likely be hurt or angry. But the *exact same review* under a four-star rating will make their day. Subjectivity is too much of an issue, to make a long problem short.
So if I've reviewed one of your books, don't worry, I still like it, and the review will still be there. Just not the star rating. And it'll take me a while to work through them all.
Amazon, unfortunately, forces you to pick a star rating (that is, I haven't found a way around it yet), so I'll have to decide how to handle things over there. Hm.
