> It is entirely normal to have friends you aren't super close with but still want in your life. A lot can be reached through iMessage/SMS but a ton of stuff happens on social networks nowadays.

I am in a similar position, and have no social media. To echo some of your points, when I first left FB there were some events that I missed out on that I would consider high importance to me. At first, I was shocked, I tried to hide it with the "real friends with mail me!" excuse, but I was still "disappointed" (for lack of a better word)

I'm lucky enough where a observant extrovert in my social circle noticed my preferences, and now they email/text me about most events. I try to keep in touch with the rest of my friends over phone, and people i'm not super close with over email. I don't do the best job, but I don't miss FB
