After going to a chiropractor and having a billing dispute with the professional neck cracker, Christopher Norberg posted a negative review on Yelp, calling the guy a liar. The "doctor" in question, Steven Biegel, then in turn hit Norberg with a lawsuit. The review happened over a year ago, and Norberg has created his own site to tell his side of the story. According to his attorney, Michael Blacksburg, "If Christopher loses then anyone on Yelp who writes a negative review better be careful ... This strikes at the heart of Yelp's business model and other Web sites that provide a bulletin board for people to state what they think of businesses in their community."
