FWIW, I won't be switching to gitter or slack - I find the push

hours - or days - at a time.

If you read my blog, you'll know this already – I also find Slack tiring in exactly this way.  I acknowledge the usability benefits over IRC, but the effect of those benefits is mostly just prompting me to spend more time staring at chat.  Which is not what I want to be doing.
