writes with this excerpt from the SF Chronicle:
"A San Francisco chiropractor has sued a local artist over negative reviews published on Yelp, the popular Web site that rates businesses. Christopher Norberg, 26, of San Francisco posted the first review in November 2007 after visiting Steven Biegel at the Advanced Chiropractic Center on Valencia Street. In the six-paragraph write-up, Norberg criticized Biegel's billing practices and said the chiropractor was being dishonest with insurance companies. ...The Electronic Frontier Foundation, a local nonprofit that supports free speech online, is considering helping with Norberg's defense. Matt Zimmerman, an attorney with the group, said Biegel will get far more negative publicity from filing the lawsuit than from a bad review on Yelp. He said the foundation is seeing more and more cases of people trying to use the courts because they're unhappy with postings on the Internet."
