I do. I've only ever worked for public universities or state owned organizations, so every work email I've ever written is theoretically accessible via an open records request. I write every email as if it's going to be published on the front page of my local paper.

As a result I don't use email very much.

I absolutely do. If I'm typing it I'm checking myself just as if I were speaking across an open plan office.

The only way you'll ever know what I actually really think about something controversial is if you ask me face to face, or maybe, on a phone call.

I'll echo the other comments here, too. I never put anything in writing that I'm not comfortable being published publicly. Working in the public sector and being subject to public records requests, and working in the private sector and having my emails quoted by opposing counsel to a judge during a lawsuit both taught me the value of being exceedingly careful in what I write.

I know I do and im sure others that are often under regulatory scrutiny do as well.
