A new article out today in PCMag.com shares a few remarkable statistics about the recent growth of social networking on the Internet. Nearly 70% of all web users visit member communities regularly and the 35-49 age group grew by over 24 million people in terms of embracing popular social media sites. Use by seniors 65 and over also grew, but at a modest 7%.

"The U.K. also proved to be the country most open to social-networking while on the go, with 22.7 percent of mobile Web surfers, or 1.96 million people, visiting a mobile version of a social-networking site. The U.S. was second, with 19.2 percent."

The 2007-2008 study by Nielson included the United States, Brazil, the United Kingdom, France, Germany, Italy, Spain, Switzerland and Australia.
