If you want to listen in on pretentious gobbledigook jargon, you'd be hard-pressed to find more fertile ground than the breakfast buffet at a Marriott hotel. And it might surprise you to learn that there really are people who want to do so. The recently-formed JLA (Jargon Listeners of America) claims a membership of over 3,000, and regularly organizes field trips to Starbucks coffee shops and ad agency account guy conventions. If you happen to see a table full of corporate types and behind them a gaggle of little old ladies in cardigan sweaters, scribbling in notebooks and giggling, you'll know you're in the presence of the JLA.
