Poll: Rich people sign up for social networks

Most wealthy individuals have signed up for social-networking sites, according to a poll released Tuesday by SEI, a wealth-advisory company.

About 70 percent of such people have signed up, a rate that is considerably higher than the general population, according to the poll, which placed that number at about 61 percent.

Most wealthy individuals have trouble finding time to use social networks, however. Only about 18 percent said they use the sites on a daily basis. Read more about the poll here.
