I have a slack workspace that has several bots, some listen for specific keywords and or phrases around the web and post to the relevant channels. Other bots remind me if I'm slacking off (maybe stayed a little too long on youtube), remind me of appointments, to drink water, if a stock price falls and some more. Also have filtered rss feeds for business and finance news etc. All of these bots also have custom identities that make it much more engaging like Axelrod is my bot for finance related news.

Others tell me if my server is getting swamped, forward important emails like renewing a cert, a deploy failed, bug in prod or something else that requires often immediate attention. Chat widgets from sites in production also go directly to Slack so I can reply quickly if needed. (Gmail, Sentry, Freshchat, Ploi etc, integrate them all and filter out what's critical).

Everything generally operates on a 15 min interval or so it's not noisy and I've pretty much tuned it to only receiving specific stuff I want to see. Having a central assistant like hub to go to is very useful and time saving.
