Avoiding internal jargon is a good idea, or better, use the appropriate jargon for the audience. Jargon is an efficient shorthand, but only within the community that has a common understanding. I used “set top box” above, but inside Netflix, we say “STB”. And yes, our STB plans are public now, see the Roku box and Monday’s Xbox announcement.

Another example, I had a friend with two business cards. For the US, it was “Donn Terry, PhD” and for Japan, it was “Donn Terry, Project Manager”. Each one matched the local status systems. Also, in Japanese, a speaker needs to know their relative status in order to say anything, because the grammar changes depending on that.
