Your parents have already friended you, and now Grandma might too. A program sponsored by the AARP and the nonprofit Older Adults Technology Services aims to help low-income seniors get online. Each senior participating in the program in Washington D.C. received a free iPad and classes on how to use it, including tips on protecting privacy online, how to get started with social media, and  how to manage and interact with the technology, especially for those with shaky hands or a phobia of pop-up windows. Many of the senior participants found that engaging with social media allowed them to get in touch with old friends, find information about their interests, and diminish loneliness and isolation. AARP and Older Adults Technology Services are running a similar class in Sioux Falls, S.D., and evaluating whether to launch it in other cities throughout the country.
