The biggest problem that sucks about discord is that it isn't normally publicly searchable. And it seems to be a modern replacement for internet forums which historically were publicly searchable and often had a lot of great information about various hobbies and things.
This is a feature of the platform, not a bug. Because of the lack of discoverability people act more genuine, for better or for worse, than public places like Twitter, Bsky, Facebook, Instagram, etc where you have to maintain your public image and/or act like HR is watching over your shoulder.
That being said, this feature also makes Discord inappropriate for things like release announcements, patch notes, etc. which should be publicly accessible.
