Reservoir Hill writes: "The "I'm Feeling Lucky" button on Google's search page may cost the company up to $110 million in lost ad revenue every year according to a report in American Public Media's Marketplace. Tom Chavez says that since the company makes money selling ads on its search results page, the 1% of users who use the "I'm Feeling Lucky" button never see Google's ads because the button automatically directs them to a non-Google site reducing Google's ad revenue. So why does Google keep the button? Marisa Mayer, Google's vice president responsible for everything on the search page, says that "it's possible just to become too dry, too corporate, too much about making money" and the "I'm Feeling Lucky," button reminds you that "people here have personality." Web usability expert Jacob Nielsen says the whimsy serves another business purpose: "Oh we're just two kind of grad students hanging out and having a beer and having a grand old time," not you know, "We are 16,000 people working on undermining your privacy.""
