Oh awesome! I hadn’t seen that before but that’s really cool to see. I’ll definitely have to read through that thread in depth to see what people are saying about it (I skimmed but just saw bug reports at the end).
However, I would say this requires in-depth planning and discussion around how we’d approach it because it has the potential to distract from building valuable community content in topics. For instance, if I’m a new user and I know nothing about programming, I’d be less inclined to make a new post with an accurate title and structured content than I would be to go to a chat and say, “help plz, my code doesn’t work.”
As @dannytech mentioned above, chat is ephemeral and is basically unusable after an hour, unless you were actively engaged when the messages were being sent.
Even this plugin looks like it’s going to require some research and more than just a couple button clicks to get it setup and running in a way that would be productive and valuable. That said, Discourse uses Ajax requests heavily so you can see updates to a topic while you’re viewing. Very chat-esque
