http://www.w3.org/ns/prov#value | - WeeSpring, a TechStars company, particularly admires, ???what [Yelp has] done to maintain the authenticity of their reviews, especially their consumer alerts tool, where they red-flag businesses that are caught buying reviews.??? (Yelp places a consumer alert banner on pages of businesses it believes have paid for reviews, though takes it down after 90 days if the business has cleaned up its act.)
