Facebook Legacy

This is a product concept I've been thinking about for some time and wanted to put out there for discussion. I do not work for Facebook.

By marking posts as Legacies, your favorite memories would be shared with family for generations. Imagine receiving a photo today from your grandparents, taken when they were exactly your age. The idea here is about preserving and repeating important life moments rather than letting them disappear down the Timeline - or worse, limiting their view to just your current list of friends after death.

As a side effect, by tagging a post as a Legacy, you're in effect scheduling it as an event to repost to ancestors in the future who would be seeing it for the first time. With millions of these updates scheduled for the future, Facebook would have a stronger outlook for the long-term and greater odds of future generations coming on as users.
