If yelping doesn't sound like fun, you may not be as hip as you think. Through its Web site, Yelp.com, the company offers user-generated reviews about local businesses and service providers, including restaurants, bars, salons, retail businesses, doctors, and museums. The site has adopted a social media-friendly interface; users can create and maintain profile pages (complete with online friend networks and photos), where they can blog to their heart's content on experiences with various businesses. Yelp has established a foothold in dozens of major metropolitan cities in some 35 states across the US. The company was founded in the Bay Area in 2004 by Jeremy Stoppelman (CEO) and Russel Simmons (CTO). [Description from Hoover's]
