bs. discord is absolute trash for anything but live chatting. it does nothing different from plain old irc with a bnc and bots. they just took irc and made it easy for stupid people to use and slapped voice comm on top; which also already existed. using it as an archive, broadcast and support system is like trying to use a hammer to screw in a screw. people just use discord because people use discord. just like people just use facebook because people use facebook.

if you want to manage a community, you should use discourse. it's the most modern alternative. if you want a public chat, use any chat you want that supports public chat, the only difference between all of them is what level of privacy they provide.

What makes discord "great" exactly?
