In "Internet Study Finds the Persuasive Power of "Like," " Kenneth Chang writes about new research that suggests popularity breeds more popularity online. WHAT findings did scientists report on Thursday on the Web site of the journal Science? WHAT implications does the study have for "hype" on the Internet? HOW does the study call into question the reliability of "wisdom of the crowd" ratings on Web sites like Yelp and Amazon? WHO are the authors of the study? WHERE are they from? HOW did the researchers conduct their experiment? HOW does the idea of "cumulative advantage" work? Are you more apt to "like" something online if it has already been liked? Does this research confirm your own experiences? WHY do you think people are more likely to "like" what's already popular? WHAT implications do you think this research has for online consumers and social media users? What about for businesses and advertisers?
