Many adults are not sold on social networks

Social-networking services such as Facebook, MySpace and Twitter may be generating lots of buzz. But old-fashioned, non-digital, face-to-face conversations aren't out of vogue just yet. About 87% of 1,000 adults questioned in June said they prefer to deal with other people in person instead of via computers or smartphones, according to a survey from Brightkite, a mobile social-networking service, and GfK Technology, a market research agency. What's more, half of the respondents said that they do not use social networks.
