Right now, ratings are mostly cosmetic.  They still provide useful information to buyers, but they could become a useful tool in finding creators.  Allowing browse and search sections to be sorted by rating would be very useful to help find quality creators faster.

Admittedly, it won't be super useful right this moment, and would only separate out brand new from established counts since most sellers who have ratings have high ratings, but as the site grows having this metric and tool in place will help buyers and quality sellers alike.
