For the people who you care about, you can contact them directly and set up a time to meet to catch up. Or catch up over text or email. Or start a messaging group with mutual friends and keep each other up to date that way.
My feeling is that if you only get updates about someone's life via their blasts on social media, you're not really friends. So why do you need to hear about all that stuff?
Right. You post it on social media to the exact same reason you would post it in the newspaper.
And you would have to understand socialization if you wanted to know why people published life events to the newspaper - births, deaths, graduations, marriages, etc.
Not everything in the world is for your bestest friends. It’s OK to not have close friends.
