Well, First off, Discord SUCKS, Im pretty sure even if you dont care about privacy or stuff like that, You would still know

Why even use it?

People only seem to use discord because others do, Same argument applies to whatsapp, But i dont really see the use case for discord

Maybe I'm out of touch, But a "Gaming Chat Program" Doesnt make sense, Yet, Dispite it being made for gaming, Many people just use it as their main messager

People may say its for gaming because of rich presense, But XMPP has this, Rich presense is not a new thing, Hell, I Would say XMPP does better rich presense, As if people care about rich presense

I Just dont see whats the hype with discord

Privacy, And Alternitives

Discord... Suprise, Has terrible privacy

I Am not going to list all privacy concerns here, But you can read up on it here.
