Nearly 90 percent of U.S. adults prefer dealing with people face-to-face, not through high-tech ways, a market research survey indicated Monday.

In addition, half the respondents said they didn't even use Internet or other digital social networks, the June survey of 1,000 adults by Brightkite Inc. mobile social-networking service and market research agency GfK Retail and Technology found.

Women prefer face-to-face get-togethers 70 times more than using social network services, the survey indicated. Men prefer it 33 times more.

"Social networks are a great tool to connect with people, but they don't replace the pleasure we get from meeting friends," Brightkite Chief Marketing Officer Rob Lawson told USA Today.

A survey for LinkedIn Research Network by Harris Interactive indicated nearly 70 percent of 2,025 adults questioned in June said they didn't know enough about the Twitter social networking and micro-blogging service to have an opinion about it.

Twelve percent said the service was used only by young people and the media, the survey found.

The Brightkite/GfK survey had a margin of error of 3 percentage points. The LinkedIn/Harris survey's margin of error was 2 percentage points.
