User Reviews as Good as Professional Reviews?

Make sense to me, of course I am a big champion of reviews. ChildBook has over 1000 reviews of our learning Chinese materials.

Key Points:

1. Overall expert ratings correlate to customer ratings on Amazon. And yes, I know about the reviews of classics that are negative, such as 1 star reviews of the Catcher in the Rye.
2. Customer reviews are better for new authors. Professional reviews have a biase against new authors.
3. Professional reviews are influenced by gotten attention in the press. Customer reviews are not.
