Very true, wasn't there an adage about to find out who your real friends are just post that you need help moving and see how many show up. It's like being a cable cutter, at first you think you will miss out on a lot but you quickly realize that it ain't so bad and that the world didn't end.

I also find that (at least in my social network) many friends don't broadcast their lives (and rightly so), so you need to talk to people anyway to get the real picture. What you see in a social network is limited to content that people want to broadcast.
