Discord is a black hole in the internet. People have discussions you can't search for and isn't indexed on Google etc.
It's convenient but it's worse than a forum for creating knowledge people can search through later. It's a shame it's used for such interesting discussion.
It's a chat room. The conversations are disposable, it is part of the medium. Having a record of discussion is not really what interests me about instant messaging.
I personally like reddit for public discussions. r/fusion used to be a ghost town with crackpots a few years. These days there are occasional good discussions and the crackpots are chased off.
