I've developed much more appreciation for precision in communication over the last fifteen years due to the necessity of frequent communication with German engineers. They speak English very well, mostly, but it is quite easy to confuse them when too many pronouns or more obscure terms are used.
I think that sometimes there is a perfect word that is not commonly used but in some certain instance is most fitting and completes a thought most succinctly. When done artfully, the meaning becomes perfectly clear by context.
On the other hand, using words that befuddle---no matter who the audience is, is just pointless noise. Captain, in Cool Hand Luke said it best:
"What we have here is a failure to communicate."
