And again, I think it comes down to culture. In your workplace, you're in a room with your coworkers: do you ask "Excuse me everyone, could I have a moment of your time? Does anyone know the status on the internal project Crusade Against Initialisms? Thanks in advance!" or do you say "yo what's the latest on CAI?". In our org, Slack is the same as talking in person (since we, you know, can't do that anymore thanks to WFH and whatnot).
I don't think it's so much a corporate culture thing as a context thing. There are certainly channels in my work Slack that I feel compelled to add more kindness phrases to when engaging.
Following your metaphor: if I were in a room with a couple hundred other people I _probably would_ say "excuse me" before shouting a question.
In both instances they disturb the train of thought which is why I am not a huge fan of open plan offices, nor instant messaging during coding and concentrating. It’s why libraries don’t have buzzers and bells going off.
