I went from a company of 900 people to a company of 80 and wow what a difference. There was so much noise in the larger company that I'd spend probably 2 hours a day reading slacks (and they rarely threaded messages even). Fast forward to here and it's like a breath of fresh air. They're very conscious about threading and while I now have time to read every thread I can tell at a glance if I should. Doesn't really help your problem except to say that assiduous threading does seem to make it easier at a certain scale to know which messages to ignore.
