I personally don't have it. Don't have snapchat or a smartphone even. I have a fuckton of friends and I am fairly popular, but I've always been afraid to seem like an attention whore. Even when people try to take pics of me I get kinda nervous because I don't wanna pose (and be a poser). It's so late in the game now that I just can't jump into it anyway.
I do use facebook (without posting pics) and chat clients like discord, slack, telegram … I just feel like I've gone over all of this already when I was a PC obsessed kid on phpbb forums rping in a harry potter-like universe, making anime review sites on freewebs.
