Yelp.com, one of the top 100 websites as of 2008, is a Web 2.0 company that allows users to review directory listings (restaurants, businesses, parks, etc) and to interact with one another in a style similar to Facebook and MySpace.

Launched in 2004 in San Francisco, Yelp.com has approximately 10.6 visitors per month. In early 2008, the company expanded with a new office in Manhattan, NY and by listing directory information in Canada, allowing users to review and discuss locations in that country. Profitability is expected in 2009.
