65 -- That's the percentage of adult Internet users who say they use a social networking site like Facebook or LinkedIn, up from 29 percent in 2008, according to the Pew Internet & American Life Project.

As people of all ages increasingly connect online, sharing status updates, pictures, thoughts and feelings, let's hope they can enjoy the opportunities technology grants without cutting down on the face-to-face interactions that have sustained mankind forever. hN
