A meditation on Slack at 1 million daily users:
Slack is not perfect. Months ago, its founder, Stewart Butterfield, told me you would soon be able to leave emoji comments on Slack messages. For example, if someone said something poopy, you could comment with a poop emoji, and so could your co-workers, and in time you would return to view the poopy message, and it would have eight poops next to it. This hasn’t shipped yet, and I for one would like to know what’s going on there.
