Stories like this make me wonder if there should be some sort of law/regulation to ensure data availability for a certain amount of time if a site is shut down - in a similar way that there's a process for the government to force companies to issue safety recalls. There's an interesting philosophical question here - if our data makes up part of our memories, is negligence of that data tantamount to, say, negligence in making football helmets that could permit head trauma and potentially "erase" the ability to access memories?
