[Yahoo Developer Network] With the Yahoo! Mail Web Service APIs, you can build applications to perform tasks such as listing messages, displaying folders, and composing and sending messages.

First we announce unlimited storage. Now there’s an API around mail. Then I read this:

“Yahoo! Mail offers an incentive for developers to build applications using the full functionality available for premium Yahoo! Mail accounts. Specifically, Yahoo! Mail provides a commission of $10.00 for every new Yahoo! Mail Plus account referred by developers.”

Good stuff. Now go play.
