The role of social networks is especially of interest to pharmaceutical companies who spend approximately "32 percent of their marketing dollars" attempting to influence the opinion leaders of social networks. Several websites are beginning to tap into the power of the social networking model for social good. Such models may be highly successful for connecting otherwise fragmented industries and small organizations without the resources to reach a broader audience with interested and passionate users. Users benefit by interacting with a like-minded community and finding a channel for their energy and giving. Few social networks currently charge money for membership. In part, this may be because social networking is a relatively new service, and the value of using them has not been firmly established in customers' minds. Companies such as MySpace and Facebook sell online advertising on their site. Hence, they are seeking large memberships, and charging for membership would be counter-productive. Some believe that the deeper information that the sites have on each user will allow much better targeted advertising than any other site can currently provide. On large social networking services, there have been growing concerns about users giving out too much personal information and the threat of sexual predators. Users of these services need to be aware of data theft or viruses. However, large services, such as MySpace, often work with law enforcement to try to prevent such incidents. In addition, there is a perceived privacy threat in relation to placing too much personal information in the hands of large corporations or governmental bodies, allowing a profile to be produced on an individual's behavior on which decisions, detrimental to an individual, may be taken. Social network services are increasingly being used in legal and criminal investigations. Information posted on sites such as MySpace and Facebook, has been used by police, probation, and university officials to prosecute users of said sites. In some situations, content posted on MySpace has been used in court. 11.According to the text, social networks _______ A. are being used by businesses for marketing. B. are about friendships.
