My friend John Barry spends time on the Sierra Club’s website (no, that is not the sign of the apocalypse) … he found this gem:
If you’re already on a company’s mailing list, contact it directly (by going to its Web site or calling customer service) to keep its fiber-intensive material out of your mailbox. To prevent new companies from harassing you, get on the “do not mail” list by writing to Mail Preference Service, Direct Marketing Association, P.O. Box 643, Carmel, NY 10512 or registering online at dmaconsumers.org/cgi/offmailinglist. Unfortunately, the system doesn’t distinguish between greedy corporations and noble nonprofits, so this action may cut you off from worthy charitable appeals.”
My emphasis added. In other news, I think I convinced myself that global warming “has to” be good using a standard application of utility theory. I’ll work through the simple analysis in the next day or two.
