Re: Without Facebook...
Couldn't give a shit about Facebook, but WhatsApp was crucial while MrsO and I were separated for four years due to the Hostile Environment. Whether it was talking about the kids and how they were getting on at school, our application for her visa, just chatting and saying "I love you" on a daily basis, this would not have been possible via phone or snail mail, even email would have been a bind.
In the place where she was, rural east Java, simple connectivity via WA was about the best we could hope for. It saved us, in many ways.
But FB itself can go and pound sand.
