The Center for the Digital Future at the University of Southern California surveys 2,000 households each year to find out how online technology affects Internet users. Findings in the latest report show social networks are increasing and a majority of users report feeling as strongly about their communities online as their real-world communities. In fact, 75% report participating in communities related to social causes on the Internet. Nearly 90% are involved in social causes new to them since their involvement with online communities. The growth of online communities is creating a range of new sources for positive social change. Some disadvantages of social networks deserve consideration. A majority of parents expressed discomfort about the increasing amount of time their children spent in online communities because it takes away from time spent with the family. Researchers at Case Western Reserve School of Medicine surveyed 4,200 high school students to determine the association between use of communications technology and health behaviors. Results indicated excessive users of texting and social networking are much more likely to engage in unhealthy behaviors. Finding ways to improve social networking of children should be assigned high priority. Some possibilities are listed.
