149 Million is still not much compared to the 6.92 billion people on the planet, most people in the developing world still do not have access to a computer (more mobile phones than toilets in some countries.)
I do still know a few people who won't use anything more complicated than a mobile phone and will refuse to even get an email address.
For a lot of couples I have found it is either one or the other who is on Facebook and keeps up to date with their friends.
I have stopped using the Events tab to check for upcoming events as there are just too many now. Due to what I do in my spare time I have a lot of people I only "sort of" know, who expect me to know them when I see them.
I do go out 100+ times a year to see and photograph live music and it has has helped with that at least.
