I used to work at Dell selling computers to the consumer market.
This is the trenches of selling.
I could tell you about how your flat panel monitor would reduce eyestrain and cut down power usage and why a Centrino processor would make your computer run cooler and, therefore, extend the battery life. I dealt with hardcore geeks and some of the least technically savvy people on earth. Needless to say, it was a learning experience.
I’ve also sold ecommerce software to mom-and-pops and to the likes of the Barack Obama campaign and Crutchfield. That means I’ve had to explain what CSS is to a total newbie, but I’ve also had to explain the exact PCI settings in place for a hosting environment.
I’ve seen too many Web sites created by Web developers and designers who have never had to explain a product to someone. If you are a developer explaining to a developer, that’s one thing. However, too many products on the Web are actually consumer products that never seem to escape the echo chamber of the Web geek, and that is a shame.
