In 2002, Naver set up one of the first Q&A webpages, Knowledge iN. The service allows users to post questions on any subject, and select from answers submitted by other users, points are awarded to users with the most helpful answers. In this way, Knowledge iN was an early example of harnessing user-generated content to expand the amount of information available on the web, particularly in the Korean language. Bradley Horowitz, Vice President of Product Strategy at Yahoo!, has cited the South Korean service as the inspiration for Yahoo! Answers, which was launched three years after Knowledge iN.
