No one is one discord because its UI is impenetrable. Amazing VOIP though.

Discord is more of a small-group or individual communication platform. I don't think it's suited as well for the one-to-many or feed-based appeals of social media such as TikTok. (Large, public Discord servers absolutely exist, but they're often themed around something specific; and even if they weren't, you can't just have an algorithm determine which messages in a channel you do or don't see.)
