Re: WhatsApp too?
Try getting by without it? Can't be that difficult. Humanity has managed to do without it for several millennia. I find e-mail and using one of the mobile phones rarely used facilities, making a call, seem perfectly adequate for keeping in touch with people and even, gasp, arranging to meet face-to-face.
Then again, I have a lot less than the several hundred friends that most facebook users seem to have, so it's probably easier for me to interact with them without the aid of Mr Zuckerberg's (dis)services.
