The killer app for getting the elderly online and using computers/tablets/smartphones has been Skype, in my experience. Specifically, video chat. It's revolutionised communication with family who live far away. I suppose these days FaceTime would be equally appropriate. From there it's a slippery slope for most of them. The retired in my partner's and my family now spend more time playing video games than those of us in our 20s. (they simply have more time to spare)
I could see them picking up on something like this if they could overcome the trust barrier. Most 50+s I know don't trust Facebook and don't have an account there (I don't trust them either, but I'm in the minority in my age group).
