It does. Zulip calls what Discord and Slack refer to as "channels", "streams", and what Discord calls "threads", "topics". Zulip's superior topic UX was why I went with it over Slack & Discord. Now Discord has feature-parity there and even more with 'private' topics/threads. I have to create a separate channel/stream if I want some topics to be private. So now, since my users love Discord so much, I'm going to be fending off requests to move over to Discord, where the conversation data is locked in and cannot be self-hosted or exported. Good for Discord, but I admit I'm not looking forward to said conversations.
