I’m 33 and share a similar experience, except that I’ve found Instagram in particular to be an even better social experience than the old days of IM.
I regularly meet people I follow in person if they come through my town, or if I come through theres. And, when I make a new acquaintance, we stay in touch and learn more about eachother in preparation for our next chance encounter. My group of friends is lager than ever, though we don’t meet in person as often as a traditional local relationship.
