Oddly, I'm 90% sure this makes me a bit more pleasant around the office, and especially by email.
My internal tact-meter doesn't so much check "is this a good idea to say?" Rather, it checks, "am I in a good enough mood to deal with the fallout of saying this right now?"
Today, the answer is generally, "could this wait until tomorrow?"
And on the first day of the awful new time-tracking system, too. Guess I'll have to save up snark for later.
