Zulip has a tiny change: you have to make a conversation have a point up front by giving it a thread title. random convos can happen in the ‘random’ thread, so it includes the previous model.
That’s not a tiny change. That’s a huge change. That’s the difference between an e-mail listserv and IRC (or a PHPBB forum and IRC). It seems like what you’re saying is that you prefer topic-based threaded conversations to the free-form “chat” model. That’s totally valid! However the mere act of requiring a topic, in my experience, totally changes the way people approach and interact with the software, and, as a result, changes the nature of discussions that take place. Personally, I think it’s a positive change, but lots of people disagree.

Except that you can have a thread just for conversations. It subsumes the chat model.
