The Economics of Spam

higgins writes "The Wall Street Journal has the best story I've ever seen on the economics of spam. A self-described "spam queen" (Clean link; should work for non-subscribers) talks about not just the millions of emails she spews, but what it costs per mailing ($250 for 500k emails), what the response rates are (1-2 one-thousandths percent) and what she actually makes. (40% of each sale of one product: anti-spam software)."
