Right before my eyes, I saw friends on Facebook go from living, breathing creators of peppy status updates to unreachable wall owners who will never post again; their pages left to a mournful public, filled with both dear friends and casual acquaintances who, for days, months and even years after, will drop by to post prayers and recanted memories on the wall of the deceased.
In most cases, there is an announcement. Some friend or family member will take the responsibility of delivering the sad news to a group of friends. If, prior to death, an arrangement was made that allowed for a designated person to fully access the account, then the page could be maintained indefinitely.
