>Our PM looked around for teams willing to use our service, and found the Gmail team very receptive. A few engineers integrated it in about a week and we launched that "send money" button on Gmail at Google I/O. Could never get over how Gmail had "send money" but Google Wallet didn't. (They eventually changed their mind, of course.)

Thanks for the insight on why Google makes so many braindead decisions. It's so frustrating I'm ready to abandon them entirely.
