I don't get Discord at all. It's like a bad chat room. From my experience, either the chat moves too fast to be useful or no-one replies which is also not useful. It feels spammy, has lots of notifications and overlays that I don't care about.
The problem is that Discord is increasingly being adopted by communities where voice isn't used and where ephemeral chat isn't helpful. E.g. All these crypto discord communities where it's impossible to find out what's going on unless you check the channel 24/7. A traditional forum would work much better for most of these cases.
The fact that Discord are trying to grow aggressively pre-IPO isn't helping.
