>Having said that, everyone also knows there are things you put in email and things you only discuss face to face, or over the phone.
A lot of people don't know this. One of my favorite classes in business school was "Business Communications." a lot of the stuff seemed really basic, but I'm amazed how much of it is disregarded in the wild.
First job out of school (early 1990s), working at a "big" consulting company. All the new hires had it drilled into them that you do not talk about work outside of work. And you never discuss anything client-specific in public, on a plane or in a cab, in a restaurant, etc.
Email wasn't a worry, nobody had it then. I think they had an internal system of some sort but the line staff consultants didn't have access.
