It certainly did, as someone points out in the comments at the Times. Craigslist was littered with ads for Yelp reviewers a few years ago when I was last looking for a job.
That's not useful, other than to find the address of a place that I already know about. A vote of 4 seems to be the safe vote on Yelp.
'Responding to criticism from business owners that some user reviews are unfair, Yelp also recently introduced a way for the business owner to send a message back to a reviewer. If the reviewer doesn’t choose to write back, the business owner can’t send a second message.
But Mr. Stoppelman said that the site deliberately tilts its rules to support the reviewers. “We put the community first, the consumer second and businesses third,” he said.'
