Let's be clear: Poor use of jargon can cost you. The Crazy Egg post cites a test for online conversion in the financial service industry. They tested the term sales tax refund (which is what most people call it) against sales tax recovery (what the experts call it). A one-word difference.
The non-jargon version got 31 times the response of the jargon version.
I hope the folks who wanted to look smart by using the jargon term are feeling stupid.
