I actually had an idea for a sort of opposite slackbot: It would sit in all channels and keep track of the messages sent by each person. Then it could calculate how many man hours each person's messages had caused others to spend reading them. It could give you weekly feedback, and encourage you to focus your communication, and avoid spacing it out, but handling things in concentrated bursts, so you don't keep re-distracting people. Maybe it could even have weekly leaderboards with the people that managed to communicate the least disruptively with their colleagues.
