>Facebook is a chat/opinion/vanity medium, are we really saying that losing facebook (or whatsapp or whatever) access is a national emergency?
Not a direct answer, but this triggered me to wonder how many relations/connections would be lost because people have no other details of each other than what's on facebook.
Sadly that's true, but the blame for this single point of failure falls entirely on those people. In this day and age it's inexcusable not to have multiple ways to contact people you care about.
I don't think it's fair to individualize the problem in that way. Just like yesterday with our security thread, it's not reasonable to expect every individual to go to the extremes necessary to prevent data leakage. There's plenty of excuses and the one you're most likely to get is "I didn't think it was a problem" or maybe "I have a busy life, how can I be expected to do/know that?"
