The thing though is that it costs a lot less resources to deliver a
typical newsletter by e-mail than over the web. So, if you put something
on the web, and 140k people actually *read* it, you'll have spent more
horsepower and a lot more bandwidth (given that on the web you'd feel
obliged to include an image or three to keep up with the Joneses) than if
you'd mailed it to these people directly.
