In Zulip, you subscribe to streams. Streams are like channels in Slack or IRC.

Each stream message also has a topic. Topics are unique to Zulip.

Topics make it easy to catch up after a day of meetings.

Messages sent hours apart are linked in the same topic.

Without topics, it’s hard to catch up efficiently, and hard to participate in conversations that started while you were away.
