As the article points out, Yelp is not just about restaurants. It's good for everything from hair salons to insurance brokers. The courageous Megan C. even used Yelp to share thoughts on the doctor that performed her anatomical modification. Now that's what I call broad coverage.
Among the many reasons Yelp is succeeding is that it easily passes the multiple choice test for consumer internet startups that I blogged about 18 months ago. Later this week, I'm hoping to post a similar multiple choice test for enterprise software companies, though I don't anticipate success with that test will lead to any articles in the NY Times Dining Section.
