The last time these people gave out their email address was in the early 2000's so I could add them on MSN. In the last 2 years anytime I meet someone new we don't exchange phone numbers or email addresses. They ask "Are you on Facebook?" and we connect there. This is becoming more and more common. I'm not saying that it is impossible to get by without Facebook just that it is more inconvenient. For me, giving up Facebook would have almost the same effect as giving up the telephone (for personal use).
