Can you elaborate? Slack's async feed used to ping me every 5 min and distract me from coding. I also found myself having OCD about going through each and every message that was sent to all channels - very low ROI obsession. I like the slightly higher barrier of having to send emails and refresh your email inbox :)
EDIT - thanks to everyone correcting me on the sync vs async! I fixed it in the original comment.
