In my previous post I didn't really explain how reviews would be rated. Here is my idea.

Instead of rating a person's reviewing ability for one value for them (like you rate Cherry 4, Bob 9, Kat 7, etc.), you would rate each individual review. Like say Kat wrote 10 reviews, everyone could rate each review a number, and the average of all her ratings would be her weighting.

So basically people would rate each review, and then the person's weighting in the total level rating would be determined by the average of the ratings of their reviews.

This way, as people write more and more reviews and get better at it, their rating will go up and they will have more say in the final rating of a level.
