It's not entirely a generational thing. I'm a lot older than you (Facebook became available to non uni students when I was 30) however, I've moved around a lot. Different countries, different US coasts, etc. As a result my friend group is spread over different continents and across different social classes—things that make picking up to go visit or reach out for a simple phone call pretty difficult. FB has been a great way to not only maintain contact with people but to reunite with people I knew in childhood and adolescence that would have otherwise been lost to me. I don't spend much time in the app at all, but I appreciate being able to reach out or to offer emotional support (congratulations, condolences) in ways that would be impossible were I working my way through a phone book every month or so.
