Jargon the Jargonarian

Observation: Effective use of jargon requires the consent, implicit or otherwise, of the intended audience.

Clearly, jargon is exceedingly useful when talking about the technicalities of any given field. However, being unable or unwilling to talk to "normal people" about a subject without resorting to jargon indicates a certain amount of laziness on the part of the speaker.

To quote _nicolai_:

It's not useful to be speaking some special Democrat-English that is only understood by the sort of person who has a callus on their finger from reloading Daily Kos all day.
