Nicole has explained it pretty well, but I'll try to add a few things.
We have a
book review grid. Here's the link -
https://permies.com/t/31762/staff-reviews/Book-Review-Grid#246938
We also have plans to introduce a dvd grid and a products/tools/that-kind-of-thing grid. It seemed appropriate to have some sort of scale for the reviews, and for books acorns seemed appropriate, as books are often like the acorn which provides the ideas which can grow into great things, like oak
trees. Most analogies I have anything to do with tend to centre around trees...
A moderator has to manually add an appropriate
thread to the grid, but once that is done any review in that thread, by any member, which includes the phrase/string '
out of 10 acorns' will be automatically picked up by the grid-making-software and the score recorded, along with who wrote the review. At the moment only 24 reviewers appear on the grid as it was getting a bit unwieldy, and those 24 are the ones who have written most reviews. We might tweak the software a bit though. Still thinking about the best ways...
So far, I've never given 10 out of 10 acorns, mostly because I tend to believe that no book is perfect and there is always room for improvement. And I don't think I would ever waste my time preparing a review for a book that wasn't worth at least a 7. I have a mountain of books to review and I'm going to concentrate on the best ones that I think will help other members most!
