As far as I understand the blockchain is permanent and open. Everything you write here will be here for posterity. I saw someone posting baby photos jokingly written as though the baby was writing it, and I just thought, there's so many moral questions hanging over that!!! I bet there'll be plenty of court cases in the future of parents by children for compromising their privacy before they are of an age of consent. And so, let's face it, seems like our governments are pretty fascist at times, there's so much surveillance, I don't feel like giving away too much of my self on these platforms. I dunno, it's an interesting topic for someone to write about here on Steemit!!!
