I think that it's just a fundamentally different way of thinking. Having a distributed team means you have to remove the "I'll just walk over and ask" mentality from everyone involved. You must resist the temptation to use slack as an alternative to in-person communication. Communication must be frequent, documented and public - someone else needs to be able to see the decisions you made.
