Good reviews don't always show up but they will market businesses to pay money to be part of yelp™ and learn how to be displayed more favorably. Unfortunately, this forces everyone to pay more for all goods and services, businesses have to spend to keep their reputation from being besmirched, easier for big business with the resources to pay more for help with this but not for small Business right here in northern IL
"To make money? Maybe. After all, Yelp™ does profit when negative reviews drive desperate business owners to buy from the review site."
