Why has it been normalized to publish almost everything in social media platforms?

Do you prefer to be more "public" in social media or you preserve your personal life.

Dont get me wrong, I do aknowledge its good to share things, yet I've been lately so many notes almost "self promoting" or public things that usually people just share privately and wonder, really.. how this will age? Is it healthy?
