That's a good point, however threads do tend to help with keeping things organized when in a channel.

It actually might be a good thing that everyone doesn't feel the need to look at slack every X minutes.

Subjective... I've found Slack and co's interspersed conversations far too chaotic, and temporal; threading is a great way of organising many different concurrent topics.

And to be clear I don't mean Slack's implementation of threads which is hiding it away in a separate panel and which doesn't get used by everyone either.
