Thanks for the feedback. Sincerely appreciate it. It's simpler for several reasons... 1. You don't need a credit card. 2. You don't need to be physically with the person or business you're paying. 4. In a store setting there would be no more waiting in a checkout line to pay. 5. Sending one Tweet is certainly simpler than pulling out a wallet, swiping a credit card, waiting for a response, then signing.
