Word of mouth is a powerful marketing tool, and businesses (not to mention the consumers), can benefit greatly from helpful reviews. Popyoular is an editorial review-based recommendation and discovery platform. It's aimed specifically at film, music, books and games. The idea is to connect a website's good content with trusted reviews and opinions about that content, helping to keep users engaged and directing them to things they may otherwise have overlooked. Popyoular's API makes it possible for developers to integrate this functionality into any other website.
