Sort Reviews by Helpfulness

We turned on a sort feature that lets you sort all the reviews for a particular item by helpfulness. Here's an example for the movie Shawshank Redemption:
















For this particular movie, there are 146 different reviews. I think it's nice to have a way to separate the quality reviews from the one liners.

The filter can be found at the bottom of the ratings list, on the right hand side.

Do does it work? I read a couple of the most helpful reviews, and to my relief.... they were quite helpful :)

I've also upped the default display of reviews to 20 - up from 10. In the truncated format, we're able to get more on the page without hurting performance.
