Do you mean Discord is a kind of community for young hackers? I’m curious about Discord because I’ve been asked about a chat app for teenagers who don’t have mobile phones.
Probably goes without saying here, but gaming tends to be an on-ramp for getting young people into computers/tech/programming. I started reversing, hacking, and writing bots for old MMOs to try to avoid the grind. I ended up enjoying writing naughty code more than playing the games themselves.
You don’t need a phone to use Discord AFAIK, but in my elderly imagination every teen is already on Discord.
