Facebook and imortality

Many things can be said against Facebook, it is a waste of time, the data is collected and sold, we lose privacy.
But when you visit the page of a dead friend, you feel that a part of her still lives. You feel that you share with her, the joy of a funny video or a enjoy with her some nice pictures.
Her clothes will be given to charity, her friends will continue their lives and forget her, her grave will be buried by grass but her Facebook page could outlive the only persons that will never forget her: her parents.
It should be a posibility to save the social network profile on a server and store it indefinitly like in a time capsule.
The people feel the need to fight the death, many make children, few build pyramids, some make extraordinary deeds: conquer Hymalaya, smash Da Vinci's "Pieta" with a hammer.
Maybe the inexpensive Facebook could be the answer, and information written somewhere, where the rain could not wash it, the fire could not burn it, indigestible for magots and bugs,affected only by the fadding memory of the people, will outlive you for centuries.
