That's my Dad who is 86 and who calls me on Skype. In fact, a few weeks ago, I forgot to turn off my skype connection during a workshop and my laptop was being projected on a screen. It was about the time that several participants in the session who were close to retirement age started to complain that they were too old to participate in social media. I swear I didn't secretly twitter on my cell phone to my dad to call in! The last time I visited with my Dad at home, I showed him youtube, videoblogging, and how to set up a blog. He was interested and enjoyed his few minutes of fame on YouTube.
Last weekend, I visited, and showed him how to set up a Facebook profile. He was curious about Facebook and poked around, but declared it "cognitive overload."
Now, my Dad has been a computer user since the early 1980s (as long as I have), so he is probably more geeky than your average octogenarian, but there are many elderly who are not. That's why programs like the Oasis program recently reported by NTEN are important to watch.
