AOL-TW billing system
Dear whomever replaces Bob Pittman: Please know, one of your biggest competitors now is eBay, especially with the purchase of PayPal. They now have a billing relationship with a large percentage, perhaps even a majority, of your customers. And they're using Microsoft's Passport for authentication.
But you won't do it. You'll screw it up. I have faith in you, AOL. I know you'll blow your chance.
