Whether or not you buy what they are selling (this is an ad for Basecamp over Slack) -- there are some great points raised that I think are worth thinking through even if you are all-in on Slack/Hipchat/etc.

I found the "one-line at a time thinking" and "announcements aren't chat" to be very elegant ways of describing some hangups I've had with group chat and I have a few very actionable changes that I hope to make in my day-to-day work life.
