The online reality today is that few Internet users say they can trust the Web sites that have products for sale or the sites that offer advice about which products and services to buy. Only 29 percent of users say they trust Web sites that sell products or services. And just 33 percent say they trust Web sites giving advice about such purchases. That compares to 58 percent who trust newspapers and television news and 47 percent who trust the federal government in Washington. This gap between consumers’ expectations and their judgments of how Web sites are doing is one striking finding of this new survey of Internet users.
