Well, I did most of my "meeting people" before I turned 30, when you have school and work pools to pull from. Now that I'm in my 30s I mostly just communicate with people I already know (though that is not strictly true, as I continue to meet new people all the time)

I use text messages, phone calls and emails primarily. People I continue to keep in touch with are neighbors, family, high school buddies, college buddies, co-workers etc. And I meet new people at the gym, in local music meet ups, etc.

I dunno where you live or who you're interacting with, but I have not had the experience you speak of.
