We love Slack! But what if we can make it even cooler? Imagine: you are geeking out with your fellow developers on Slack and you want to give them credit. Or you can write "stupidsubject--" and it automagically shows "stupidsubject's karma decreased to -2". Enter Karma Bot. This is nothing new but building one myself was a great learning exercise and a fun tool we use on our Slack now.
