Ask HN: How do you share videos and pictures with your friends and family?

As the resident technology evangelist in my extended family, I'm eager to find a solution to sharing and storing videos that does not involve YouTube or Facebook. With our family growing with grandchildren, we are in need of a service that supports uploading from mobile devices as well as consumption on said devices. This service also needs to be easy for elderly people to use (said elderly people have no problem using iPads at the moment).

Any suggestions?
