I don't think dialed-in has to be lofty. Keeping in touch with family is a perfectly fine reason. My point, and I think the point of the author, is that thinking about it before, not after, offers an opportunity to deepen your understanding. For the longest time, those in my circle who used Facebook to "keep in touch" really didn't. Sending me an apple on the latest farm game isn't a genuine interaction to me. It was only after I quit that close friends finally got the hint that Facebook was not a good way to reach out to me, despite explicitly saying it many times before. For those for whom not participating is presently unthinkable, maybe thinking it over would do some good. That doesn't necessitate changing one's choice in the end, but considering it can be useful in and of itself. Family and friends are not only on Facebook. They have a real presence in the real world. Even if one chooses to stay on Facebook or whatever social media du jour, realizing this can be immensely helpful.
