A request to everyone, for each channel:
Can we add responses to a topic by creating a thread, in stead of responding to the topic in the main channel?
This way, if somebody isn't keen on participating in a topic, they will not get notifications triggered by responses to that topic.
Currently, every new message, whether it is a brand new topic, or a response to a topic, triggers a notification.
This is a general best practice for Slack and it helps keep distractions to a minimum.
