Actually, this is a great use of technology for interconnectedness. I’ve reconnected with old friends that I would have never found otherwise that share my political and religious beliefs. It’s quite a backbone strengthener to realize how much of a non-minority opnion we are.
I, unfortunately, learned how little I have in common with anyone I knew in college and those strange years immediately after college. (Okay, so I was pretty immersed in the music and club scene, so go figure.) But I realized that I had "lost touch" with certain people for very good reasons, even though I hadn't known it at the time. It was kind of unsettling though, feeling like I wasted a huge chunk of my life on people who really shouldn't have mattered so much.
