You know you can talk to your relatives, right? If Facebook is your only source for whether your second cousin had a baby, maybe they’re not that important in your life. Which is fine - not everyone can be. But I think Facebook is a way of keeping up with people that you’re barely friends with, and maybe that’s not necessary.
I didn't come here for snarky, low-effort comments from random HN users about how to conduct my family relationships. Facebook isn't "necessary" but it sure makes my life better in many ways.
