Firstly, impromptu is bad. Work requires focus, not "oh look a squirrel!" People learn delayed gratification in life. The same goes for the urgency of someone in your org randomly deciding everyone needs to talk about my random thoughts right fricking now. Secondly, messages piling up is a feature, not a bug. You engage when you need a mental break and you're in an engagement mood. If other people are in that mood at the same time, great. If not, then if you force them to engage with you anyway you are harming their productivity. People need to learn this. People get in the zone at different times and this needs to be respected.
