I am on Facebook, Twitter, Instagram, Telegram, and Lit.
I don't do much on Facebook besides keep in touch with family and close friends. The same is true with Instagram.
I find Twitter hard to follow because there is so much information scrolling through it all at once. There is just no physical way for me to keep up.
Telegram is great for following my crypto currencies, and Lit is just and easy way for me to gain some Mithril.
