Social media is no longer the exclusive domain of the young and the hip. In fact, seniors are a quickly growing demographic in terms of social media use.

The research is in, the percentage of users over 65 is up, and there are benefits to helping seniors connect. While the process of navigating the social world will be daunting for some, caregivers can help.
