Any thought to changing the Recommend Y or N to a rating system of 1-4 similar toYelp? The yes/no is an absolute and many reviews read as if they struggle to give a Yes. The ratings could be averaged and provide a score whci changes as reviews are added. Again, similar to Yelp or other review sites.
I realize this is a wholesale change that would require a lot of work. Maybe consider for a future enhancement.
