My initial suggestion is just to make it so there is some way to see all ratings vs seeing all reviews.  Perhaps this could be as simple as adding links and these links could be used for other things as well:

Reviews: 308 - would be a link to show reviews that can be sorted/etc as they are now in the middle, but no ratings

Ratings: 5 - essentially the same except would show ratings only.  And since ratings are supposed to be short one-two liners, perhaps text for ratings could show right on this ratings page.

You could also link Friends and Fans in the same manner if you wanted.

This is the only thing I can think of right now, but I think it would totally help those who can't find their ratings.
