Do you use a rating system on your blog? How do you feel about using the rating system provided on sites like Library Thing and Amazon? When looking up information on a book you are interested in, do you use the ratings provided by these sites (or similar sites) to help you make the decision on purchasing the book?
I do use a rating system but have been wondering whether or not it is useful or necessary. I know when I look for info on a new book I read the synopsis and reviews first before looking at the ratings. Same as with movies. You can't always trust them. However, sometimes ratings are good for quick reference or for when a review is not clear.
My rating system:
4/5 Really liked it
3/5 Liked it
1/5 Didn't like it
