Holy mail wars, Batman! The ‘Hoo is offering $10/head for new mail users. From Jay-Z’s blog:
Oh, I should also mention that if you build the next kill application and convince people to use it and upgrade to the premium version of Yahoo! Mail, we’ll pay you $10 per user. The sky’s the limit on how cool your mail front-end can be. We’ll handle the infrastructure.
So, first off: Damn. That’s a lot of cash. Says something about their belief that somebody out there can build the better mail trap. Although I’d hate to be on the Yahoo mail client team right about now.
