I've used Discord for years, and admin a small community server.
With the new video chat features, I wouldn't be surprised if we saw a B2B offering soon. I certainly hope that they do so: their platform is mature, and more useful than Zoom and Slack.
Server mutes. Local volume. Push to talk. Krisp noise cancellation. Non-hostile UX. Non-threaded conversation.
In Zoom, when the presenter shares their screen, you're forced into full screen, which disrupts my note taking flow. The meeting chat's also a joke. Sure, Zoom is a useful FaceTime alternative for Enterprise, but it isn't good for collaboration. It's very self centered.
Zoom also took the interesting stance of letting FBI/Police have access to user conversations. Discord doesn't have E2E, but they did tweet a post of solidarity.
