Zulip topics are the best implementation of chat threads that I've seen yet. You can view all of them simultaneously like a regular chat room, or focus down on one. You can mute either a single chat topic or an entire stream (channel). In most chat systems, if I don't read the messages within a day, I'll never bother reading the chat history because I have no idea whether there's anything relevant in it. In contrast, I can open the Rust Zulip once every few weeks and see if there were any interesting topics. And if you're really sure you don't want to use topics, you can always just make a single "general" topic in your stream.
