"John here," the other John said, "pioneered the concept of marketing by refusing to sell any products. It drives the market insane." - Max Barry

To get a good job in marketing, you need to market yourself.

“White coke?”
“It’s a trial product.”
“Wow, sounds cool. What does it taste like?”
“Coke,” 6 says.
“Well, yeah,” I say, “but how is it different to, say, Classic Coke?”
“It’s in a different can,” 6 says.
I wait, but 6 just looks at me. “What, that’s it?”
“No,” she says. “It will also cost twice as much.” She pours herself a Pepsi. “We’re after a more upmarket niche.”
“You really expect people to pay double for a white can?” I ask, astounded. “When it tastes exactly the same?”
6 aims a chiseled frown at me. “I didn’t say it tastes exactly the same. I said it is exactly the same.”

The atmosphere of desperate, ignorant terror essential to healthy rumors seeps away, replaced by a silent, wary paranoia. People bunker down, jealously keeping what they know, which is nothing, to themselves.
