Facebook comments, ads don't sway most users: poll
Four out of five Facebook Inc users have never bought a product or service as a result of advertising or comments on the social network site, a Reuters/Ipsos poll shows, the latest sign that much more needs to be done to turn its 900 million customer base into advertising dollars. The online poll also found that 34 percent of Facebook users surveyed were spending less time on the website than six months ago, whereas only 20 percent were spending more. The findings underscore investors' worries about Facebook's money-making abilities that have pushed the stock down 29 percent since its initial public offering last month, reducing its market value by $30 billion to roughly $74 billion.
