This explanation makes the most sense to me. I've moved away from friends in the past few years, and we use a combination of methods to keep in touch, but however you do it, it seems like they just get farther away because some things just aren't worth an email or a Facebook message. Snapchat (if they used it) would be a good way to stay casually in touch with them.
