Old but not offline!
Americans over 65 are the fastest group adopting the Internet (since everyone else is already on there!) according to this New York Times story (registration required):
According to a new study by the Pew Internet and American Life Project, a research organization in Washington, the ranks of Americans over 65 who use the Internet have jumped by 47 percent since 2000, making them the fastest-growing group to embrace the online world.
Despite the increases, this age group still has a long way to go. Only 22 percent of Americans over 65 go online, the study shows, compared with 75 percent of those ages 30 to 49. But as Americans who are more comfortable with computers gradually reach the age of 65, the percentage going online (or more precisely, staying online) should soar.
