In all seriousness: I think it’s a great idea to integrate a chat into a discourse community. In our forum we ended up only using one single channel in Rocket Chat via Communiteq integration as well as for internal communication concerning one time questions which don’t have long term value.
The only reason we are not expanding is because the chat might
a) cannibalize the activity in the forum
b) chats end up in long form discussions which are more suited for the forum
IMHO: I think there are great chat platforms out there if there is a more complex and extensive demand in a community. Hence I would love to see a more KISS chat integration that might as well act as “Private Messages v2” and later on replace the current messages UX/UI in the long run.
